CLOUDSTACK-6181: Allow RBD volumes to be resized

We don't need an external script to investigate the format of the RBD volume,
we only have to ask Libvirt to resize the volume and that will ask librbd to
do so.

Backport for 4.4, original commit: 173909e99d85cfcc85b017bc426950f9f16fddf0

>                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6181
>             Project: CloudStack
>          Issue Type: New Feature
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: Hypervisor Controller, Storage Controller, UI
>    Affects Versions: 4.4.0
>         Environment: KVM/libvirt/CentOS, Xenserver
>            Reporter: Nux
>              Labels: disk, resize, template
>             Fix For: 4.4.0

>
> Rationale:
> Currently the root size of an instance is locked to that of the template. This creates
unnecessary template duplicates, prevents the creation of a market place, wastes time and
disk space and generally makes work more complicated.
> Real life example - a small VPS provider might want to offer the following sizes (in
GB):
> 10,20,40,80,160,240,320,480,620
> That's 9 offerings.
> The template selection could look like this, including real disk space used:
> Windows 2008 ~10GB
> Windows 2008+Plesk ~15GB
> Windows 2008+MSSQL ~15GB
> Windows 2012 ~10GB
> Windows 2012+Plesk ~15GB
> Windows 2012+MSSQL ~15GB
> CentOS ~1GB
> CentOS+CPanel ~3GB
> CentOS+Virtualmin ~3GB
> CentOS+Zimbra ~3GB
> CentOS+Docker ~2GB
> Debian ~1GB
> Ubuntu LTS ~1GB
> In this case the total disk space used by templates will be 828 GB, that's almost 1 TB.
If your storage is expensive and limited SSD this can get painful!
> If the root resize feature is enabled we can reduce this to under 100 GB.
