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.

VPC is deleted on a host. This fix ensures that bridge is
destroyed.

Currently if the tunnel creation fails, there is no retry logic. Fix
ensures OvsVpcPhysicalTopologyConfigCommand updates as an opputiunity to ensure
proper tunnels are established between the hosts.
