Microversion 2.75 - Multiple API cleanup changes

Add support microversion 2.75 which implement
multiple API cleanup changes.

1. Making server representation always consistent among all APIs
   returning the complete server representation.
 - Test cases added.

2. Change the default return value of ``swap`` field from the empty string
   to 0 (integer) in flavor APIs.
 - Test cases added.
