- Router VMs don't have a chain rule with -def suffix, this fixes name and
properly removes VR vms not running on a host
- Before trying to remove dnats, filter empty/None elements from list
- destroy_ebtables_rules should check what kind of action is request to be
performed (-A for add or -D for removed) and execute based on that
- Before executing any command, log it for debugging purposes
- Method to cleanup bridge, may be used in future

The SG python script depends on ebtables-save which is not available on Debian
based distros (Ubuntu and Debian for example). The commit uses /proc/modules
to find available bridge tables (one of nat, filter or broute) and then
find VMs that need to be removed. Further it uses set() to remove duplicate VMs
so we don't try to remove a VM's rules more than once leading to unwanted errors
in the log.

This fixes the issue of Security Groups not working in case of XenServer 6.5;
- Uses nethash ipset data-structure to store CIDRs (efficient than iphash and
avoids overflow errors in case users add /8 /4 ingress/egress cidrs)
- Support for ipset versions both on 6.2 and 6.5, both have different outputs. This
fixes the issue of destroy_network_rules_for_vm failing
- Implements defensive filtering of list, instead of popping last item without
checking if it's None or empty
- Greps using names that are 'quoted' to avoid bash errors
- Before setting up new network rule, tries to clean and remove old ipset entry
- Idents, whitespace and naming fixes
PS. This is my 1000th commit to the 🐵 project :)
This closes#186

This is a defensive enhancement for KVM SG script that filters out empty string
instead of popping last item which may or may not be an empty string.

The recent discussed improvement has the risk that if 'sync' hangs, the reboot may be delayed in the same way as the 'reboot' command would do. To work around, we're adding a 5 second timeout. If it cannot sync in 5 seconds, it will not succeed anyway and we should proceed the reset.
@snuf: Could we use your OVM3 heartbeat script for other hypervisors as well? One way to do it seems like a nice idea :-)
As discussed with @wido @pyr and @nuxro added an extra log line.
Tested it and it logs fine (tested to local disk) when syncing first:
Apr 3 15:31:23 mcctest2 heartbeat: kvmheartbeat.sh system because it was unable to write the heartbeat to the storage
By the way, it did also log to the agent.log but this extra log has the benefit of ending up in the system log so you'll probably find it easier there. Existing logs:

When storage cannot be reached, it does not make sense to reboot as it will try to flush buffers, umount NFS mounts, etc. This will not work and thus cause a long delay. With this change, the box will reboot immediately (like pressing the reset button).
When there is large size VR configuration (aggregate commands) copying data to VR using vmops plugin was failed
because of the ARG_MAX size limitation. The configuration data size is around 300KB.
Updated this to create file in host by scp with file contents. This will create file in host.
Then copy the file from the host to VR using hte vmops createFileInDomr method.
In host file get created in /tmp/ with name VR-<UUID>.cfg, once it copied to VR this file will be removed.

This makes sure dom0 in xenserver doesn't get hammered
when copying templates. It doesn't make sense to use
the cache of dom0 as the template does not fit in
memory. The directIO flags prevent it from trying.

Recent versions of libvirt (at least 0.9.8) will return an int when
queried for the ID of a domain, not a string. This breaks some parts of
the `security_group.py` script which expects a string containing an
int. Notably, this breaks the part handling VM reboots which is
therefore not executed.
