[MNG-7644] Fix version comparison ( .X1 < -X2 for any string qualifier x ), 4.0.x branch

[sultan]

The current version parser does not treat .RC and -RC correctly:
actual : 1.0.0.RC1 > 1.0.0-RC2
expected : 1.0.0.RC1 < 1.0.0-RC2
 
because RC1 < RC2
how to fix : place a list item before qualifier

as a consequence for any string qualifier x:
previously:

• 1.0.0.X1 > 1.0.0-X2
• 1.0.X < 1.0.0.X

now:

• 1.0.0.X1 < 1.0.0-X2
• 1.0.X == 1-X == 1.0.0.X

Following this checklist to help us incorporate your
contribution quickly and easily:

• Make sure there is a JIRA issue filed
  for the change (usually before you start working on it). Trivial changes like typos do not
  require a JIRA issue. Your pull request should address just this issue, without
  pulling in other changes.
• Each commit in the pull request should have a meaningful subject line and body.
• Format the pull request title like [MNG-XXX] SUMMARY,
  where you replace MNG-XXX and SUMMARY with the appropriate JIRA issue.
• Also format the first line of the commit message like [MNG-XXX] SUMMARY.
  Best practice is to use the JIRA issue title in both the pull request title and in the first line of the commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Run mvn clean verify to make sure basic checks pass. A more thorough check will
  be performed on your pull request automatically.
• You have run the Core IT successfully.

If your pull request is about ~20 lines of code you don't need to sign an
Individual Contributor License Agreement if you are unsure
please ask on the developers list.
