sysctl: don't modify /etc/sysctl.confTo configure firewall rules, CloudStack modifies `/etc/sysctl.conf` and
execute those modifications. This may be harmful for several reasons:
1. `/etc/sysctl.conf` may be managed by some configuration management
system. Such a system will constantly restore the previous version.
2. `/etc/sysctl.conf` may contain additional properties that have been
changed later by some system administrator (for example, once a
firewall has been configured, forwarding may have been activated
while it is disabled in `/etc/sysctl.conf`). Executing the file
again at a later time may disrupt the system.
3. Entries are added again and again. `/etc/sysctl.conf` will contain
the same directives repeated several times.
Using a configuration file is not needed as `sysctl` is able to directly
modify sysctl values with `-w` flag.

Signed-off-by: Rohit Yadav <rohit.yadav@shapeblue.com>
Guys, can you review it? things need to be discussed:
(1) this supports KVM/QCOW2 only. Anyone want to implement for other Hypervisor/format ?
(2) The original data volume (on primary storage) will be removed.
(3) The script uses the default timeout in libvirtComputingResource. Do we need to add one in global configuration (like copy.volume.wait or backup.snapshot.wait, create.volume.from.snapshot.wait)
(4) In scripts/storage/qcow2/managesnapshot.sh, I use "qemu-img convert -f qcow2 -O qcow2" to copy the snapshot from secondary to primary (hence there is no base image file), instead of "cp -f", this is because convert is faster than cp in my testing.

Made following fixes in simulator
- Support for ScaleVmCommand/NetworkRulesVmSecondaryIpCommand in resource layer
- Added support for scaling up a running VM in simulator
- Fixed some method names not following convention
In order to test PR #725 using simulator some of these changes are needed.
Based on the way HV check is present in the scale VM API, had to explicitly put simulator related check to allow support. The ideal way would be to remove all these HV specific check from code and made them some configuration (by putting them in hypervisor_capabilities table in DB). But that will be a bigger effort outside the scope of this PR.

Default to notify only script to handle non-CLVM/QCOW cases.This relates to [CLOUDSTACK-8732](https://issues.apache.org/jira/browse/CLOUDSTACK-8732)
Before this commit the call to `getResizeScriptType` would throw an exception (earlier versions returned `null`, which was fine) - this caused the RBD case to fail. By changing the default to notify only we fix the case for any non-CLVM and non-QCOW cases, too.
This is RBD for now, but this should extend to new storage types supported by Libvirt natively in future.
This is my first attempted contribution: I can see a case for adding RBD logic to the actual getResizeScriptType call, too, but I felt that putting it `LibvirtResizeVolumeCommandWrapper.java` kept the special-casing of RBD (and comments about that) in one place.
### Caveat:
With Libvirt 1.2.2 this actually doesn't do the right thing - but it does do what the documentation *says* should be the right thing, so I'm going to test if this is a Libvirt bug which is fixed in a later version.
(To make it work I need to execute something like:
virsh blockresize --path vda --size 100G i-7-44-VM
where vda is the path as far as the *guest* is concerned, and not an `rbd/` path - which *should* work, but doesn't.)

CLOUDSTACK-8443: Support CentOS 7 as KVM hypervisorThis adds support for CentOS 7 as a KVM hypervisor. As discussed in the Jira issue, the root cause of the issue was the `cloudstack-setup-agent` script that added this line to `/etc/libvirt/qemu.conf`:
`cgroup_controllers=["cpu"]`
On CentOS 6 this 'works', but since by default no cgroups are mounted, this setting is ignored by `libvirtd`. On CentOS 7 is does not work, because the `cpu` and `cpuacct` are 'co-mounted'. This simpy means you cannot use one without the order. The config line above instructs `libvirtd` to only use the `cpu` cgroup, which it can't.
There was code added to make sure the `cpu` cgroup was not co-mounted. It did this with a shell script, but after a reboot it was gone. It wasn't reliable and not even a solution at all. I went ahead and removed the code, because the co-mounted cgroups work fine. The real issue was the config line we put in `/etc/libvirt/qemu.conf` so much better to fix that instead.
The default for `libvirtd` is to use only cgroups that are mounted. When you remove the 'cgroup_controllers' line, the default kicks in. According to the `qemu.conf` file, the default is:
`cgroup_controllers = ["cpu", "devices", "memory", "blkio", "cpuacct", "net_cls"]`
Then again, if it's not mounted, it's not used. So, that's a nice way to control it.
This works just fine for both RHEL/CentOS 6 and RHEL/CentOS 7.
Along the debugging, I came across some small issues here and there which I also fixed in this PR.
If you test this, be sure to build RPMs from this branch and install those on the KVM hypervisor.
At Schuberg Philis we run KVM hypervisors on CentOS 7 for months with these fixes. Now I took the time to fix the issues in CloudStack, rather than work around them.
@bhaisaab @karuturi could you please review this? Thanks!
Please note:
The next step is to fix CLOUDSTACK-8625 (Systemd profile for KVM Agent) as currently a sysvinit script is still used. Although it works, we do not have any systemd benefits. As it is a separate issue, I'll try to address it in a separate PR.

CLOUDSTACK-8443: detect CentOS 7.x as RHEL 7 alike
CLOUDSTACK-8443: mention the correct logfile
CLOUDSTACK-8443: display the right hypervisor type
CLOUDSTACK-8443: don't try to fix co-mounted cgroups
Signed-off-by: Remi Bergsma <github@remi.nl>
This setting works on CentOS 6 / RHEL 6 but does nothing, as
"cpu" cgroup is not mounted. On CentOS 7 / RHEL 7 systemd does
mount cgroups and "cpu" is co-mounted with "cpuacc". Hence, if
we specify "cpu" then this results in an error because it can
only use them both, or none.
By removing the setting, we rely on the default of qemu, which
is:
cgroup_controllers = ["cpu", "devices", "memory", "blkio", "cpuacct", "net_cls"]
Only if they are really mounted, they will be used. So, this will
work on both version 6 and 7.
The 'fix script' didn't work well, as after a reboot you'd still have qemu
throwing errors. Now we can handle the co-mountedcgroups.
Removed duplicate code in CitrixResourceBase and its subclassesRemoved unnecessary duplicated code by having the body of the getPatchFiles method only in the CitrixResourceBase superclass. Given that all of its implementations consisted of the same code except for the path which contains the necessary file for that implementation. An abstract method getPatchFilePath was created in the CitrixResourceBase superclass so that each implementation may return the path containing the specific file needed by that implementation.
Test cases were created for each implementation, simple as they may be. One assert is made to verify that the path returned by each implementation corresponds to the path that was previously specified on each getPatchFiles implementation.
