Maven SCM Jazz Provider should accept exit codes 52 and 53 on JazzTagCommand

Jazz scm command can return exit codes different from zero even if no error happens.

The full list of errors that it can return is listed in the documentation:

https://jazz.net/help-dev/clm/index.jsp?topic=%2Fcom.ibm.team.scm.doc%2Ftopics%2Fr_scm_cli_retcodes.html

One of the exit codes it can return is 53. In JazzTagCommand.java the provider fails if any code different than zero is returned, which makes maven release plugin fail.

A workaround is documented in the following article:
