Key Vault name too big when resource prefix uses 10 characters

[jamasten]

The name when using the max length of each naming component uses 28 characters. Key vault names may only be 24 characters long. Using a 1 letter abbreviation for the "resourceSuffix" can reduce that value to 25 characters. Using a 1 letter abbreviation for the "name_token" can reduce that value from 25 to 22 characters. We could also consider dropping the hyphens if having the full value for one of the previously mentioned components is desired.

Another option is dropping the max length on the resource prefix from 10 to 6 characters.
