Add workItem and changeset associate support for scm deliver

Maven release:prepare command is failing with below error while delivering updated pom.xml to the stream due to Preconditions configured in RTC to have comments and associated work item with every delivery.

Error code for Jazz SCM deliver command - 17

I can not find any optional parameters on http://maven.apache.org/maven-release/maven-release-plugin/prepare-mojo.html for release:prepare command which I can use and pass the RTC workitem number on command line.

Suggestion:

It will be great if you can provide optional parameters like "workItem" which I can use and pass RTC workitem number with release:prepare at command line.

Example: mvn -PmyProfile release:prepare -DworkItem=123456

So build process should associate change sets created by release:prepare with work item 123456 and deliver change sets to the stream.

As of now I have to use "-DpushChanges=false" parameter to block delivery process and I have to manually find the change sets, associate them with work item and deliver them before I run release:perform.

Thanks.
