[MRELEASE-1162] Release plugin should support parallel execution

[jira-importer]

Steven Schlansker opened MRELEASE-1162 and commented

We recently enabled parallel builds with .mvn/maven.config to improve build performance.

Next time I tried to release, I am greeted with:

Seems that the release plugin should support threadsafe execution. Thanks!
