el7+: support live storage migration for kvm by default

Considering that we have addressed a considerable effort on allowing KVM
to perform storage data motion, this PR proposes updating the
'hypervisor_capabilities' table setting the 'storage_motion_supported'
to '1' for KVM.

PRs that implemented KVM storage motion features:

Non-managed storages
 apache#2997 KVM VM live migration with ROOT volume on file storage type
 apache#2983 KVM live storage migration intra cluster from NFS source and destination
Managed storages
 apache#2298 CLOUDSTACK-9620: Enhancements for managed storage
