MSC_Tests: Support wildcarded endpoints
At the moment the testsuite is unable to detect when the call agent
performs a CRCX request with a wildcarded endpoint.
- Set a default endpoint name in cpars in case the MSC does
a CRCX request with wildcarded endpoint name.
- Detect if the MSC supplied a wildcarded endpoint name. Do
not overwrite the default setting in cpars then.
- Attach the endpoint name as Z: parameter in the response so
that the MSC knows which endpoint to use. (Unconditional,
does not harm on non wildcarded requests)
