Storage motion of vm across clusters/xenserver-pools fails in a
clustered management server setup. In xen storage motion we have to send
a migrate_receive command to the destination host, followed by
migrate_send command to the source host. The sr and network detials of
the destination host have to be passed in migrate_send command on the
source. While migrating across clusters the source and destination
resources are seperate objects. To pass this information across
resources we have to send seperate migrate with storage receive and send
commands to the resource. In a clustered ms setup these commands may
have to be forwarded to another ms as the resource may be owned by it.
The serilization of the command and answer objects fails in such case as
it doesn't understand the xapi sr and network objects. Made a change to
serialize these objects in the resource layer and pass the around as
strings in the command and answer objects. Reviewed-By: Likitha
Adds disk serial ids based on volume uuids to the virt xml. This may be useful
for appliances/software that needs some serial ids on the VM disks. This does not
impact existing/running VMs, the vm virt xmls will be updates for running VMs
the next time they are stopped/started.
For testing, disk serial (of debian based systemvm) in the virt xml matched that
in /sys/devices/pci0000:00:0000:00:07.0/virtio4/block/vda/serial.
We currently don't support scsi-blcok devices for which serial is not supported,
for this we've added a DeviceType (LUN) which may be used in future and a check
to not add the serial to the xml if disk type is LUN.

CLOUDSTACK-9062: Improve S3 implementation.The S3 implementation is far from finished, this commit focuses on the bases.
- Upgrade AWS SDK to latest version.
- Rewrite S3 Template downloader.
- Rewrite S3Utils utility class.
- Improve addImageStoreS3 API command.
- Split various classes for convenience.
- Various minor improvements and code optimizations.
A side effect of the new AWS SDK is that it, by default, uses the V4 signature. Therefore I added an option to specify the Signer, so it stays compatible with previous versions.
Please review thoroughly, both code inspection and (automated) integration tests. Currently no integration tests are available specifically for S3. Therefore the implementation is needed to be tested manually, for now...
What I tested:
- Greenfield install -> will download latest systemvm template automatically to S3.
- Upload a template/iso
- Download a template/iso
- Restart of management server -> list available templates -> doesn't download them again if available.

CLOUDSTACK-9067 - As I developer I want to remove all the unused router-shell scripts from ACSThis PR removes the unused shell scripts that were present in the ACS project. Those script were replaced by the.
Some of the scripts are used by the HyperV Resource, which were hardcoded. I took the opportunity to use the Java constants over there as well, so the next one touching the code will know they exist and won't hardcode anything.
The following task were applied:
* Remove the shell files and the Java constants that were mapping them;
* Apply the use of the Java constants to the HyperV Resource class;
* Wrap the String.format() method in the StringUtils so we can test the changes in the HyperV Resource class.
The last point was added because I do not have a HyperV test environment. Hence, I wanted to make sure the tiny code I changed is covered at least by unit tests.

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.

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.)
