Modify the CRB to implement 0.24 API version

• Make sure the functional tests work
• Make sure mysql dsb functional tests work (it also deploys CRB and validates copy restore workflow)

Having the mysql-dsb functional tests rely on the cf-crb was a mistake. This is another proof.. but never mind, I will keep it as is...

[vjtirumalai]

The functional tests are validating copy restore workflow end to end which requires a DSB and CRB.
Do propose what you have in mind for a "functional test"? Lets talk after you have a proposal.

@vjtirumalai The mysql dsb does not rely on "a CRB" for functional tests. all it needs is something that implements "shapnRest" protocol.
(The DSBs are not and should not be familiar with the CRB concept - only protocols for copying data)
Implementing a service with the "shpanRest" protocol is a few lines of code... only need post data and get data... my proposal is to implement that and not rely on a another service that might change in the future.
