Add version compatibility test

[RanVaknin]

Generating build time testing for internal consumers that might consume mixed versions of sdk-core and services.
The PR has two main additions:

• an addition of a constant value to every service's package under ServiceVersionInfo.VERSION.
• a compatibility test that will fail the assertion if there is a difference between sdk-core and the service version.

I think generating a fixture test for a code generated test might be overkill, but for better readability here is what this generated test would look like for SQS:
