[Reduced footprint] Defualt vm size should be increased

[Ksenia Svechnikova]

ISO #442

Default size of nodes launched using virt role is 60Gb. This is not enough for the controller in MOS 8.0

Steps:

 1. Update /etc/fuel/astute.yaml file, "FEATURE_GROUPS" list. Specify the required advanced/ experimental features to enable.
[root@nailgun ~]# cat /etc/fuel/astute.yaml | grep -A1 FEATURE
"FEATURE_GROUPS":
  - "advanced"
 2. Upload network-template
 3. assign virt, compute node with {"id":1,"mem":4,"cpu":2,"vda_size":"70G"}
 4. Provision this node
 5. Assign controller role to the new node
 6. Deploy

Controller node fails with "Node has insufficient disk space"

Minimal require size now is 67060.

To confirm the root cause, I've increase disk size manually at step 3: {"id":1,"mem":4,"cpu":2,"vda_size":"70G"} and error didn't occur. This could be use as workaround

Snapshot is already deleted, but I assume that we could confirm the issue without it for this case

Verify the behavior with ISO#478. Default size was increased, now it's enough
