Added test automation for SHA384withRSA CSR support

Scenario 1:
Setup master with --ca-signing-algorithm=SHA384withRSA
Run certutil and check Signing Algorithm

Scenario 2:
Setup a master
Stop services
Modify default.params.signingAlg in CS.cfg
Restart services
Resubmit cert (Resubmitted cert should have new Algorithm)
