Shorten physical resource name to custom limit

The default limit for resources is 255, which is
determined by the column size of the name columns in
other openstack project databases.

The limit for nova servers is 53 characters due to typical default
linux HOST_NAME_MAX of 64, minus the '.novalocal' appended to the name.

The reduced name will consist of the following:
* the first 2 characters of the name
* a hyphen
* the end of the name, truncated on the left to bring
  the name length within the limit

The validation fix from bug: #1238272 has been removed.
Closes-Bug: #1250291
