Support for Persistence

[AndreaGron]

Description

With this PR now it is possible to create persistent VM.
The instance controller has been updated in order to react to persistent template. A datavolume is created and it allows the creation of a pvc used to import the VM images.
It has been used a virtual machine instead of a virtual machine instance because of the need to start and stop the VMI.
