[FIXED JENKINS-9807] : [Maven Jobs] Post build deploy task : Deploy with unique versions (timestamp) should be configured by default

ViewGroups like NestedView to override)

When there are absolutely no executors for a specific label, there was an unnecessary delay in provisioning the first node for that label

Added an extension point to allow prodding the NodeProvisioner into taking action faster than it might usually.

[FIXED JENKINS-9845] reduce memory consumption of dependency graph calculation: include maven dependencies with 'unknown' version only if needed.

Fixed JENKINS-9785 : option to run maven in headless mode to avoid boring dock icon to jump and take the focus on OSX

JENKINS-9786 : Jenkins can read repositories definitions from Maven POMs to use the deploy task after the build. It's no more necessary to set/duplicate this information in the job configuration.

[FIXED JENKINS-5044] catch FileNotFoundException if mojos are executed from a classes directory instead from a jar

Pull individual Dependencys out of DependencyGroups we see in
BuildTrigger.execute and make sure to actually kick those builds off
as well, so that we can have two different dependencies (say, for
different parameters) from one upstream project to a single downstream
project.

Maven2/3 jobs using Maven3 in console output.
With Maven3 the output format for mojos has changed:
- Add a new Maven3MojoNote and use it in MavenConsoleAnnotator.
- This is sufficient for Freestyle jobs running Maven2 or 3 and Maven2/3
  jobs running Maven 2.
- Maven2/3 jobs running Maven 3 are using ExecutionEventLogger for
  printing start of mojo execution to console.

This change introduces the necessary extension point. The implementation
of this will be in a plugin.

GlobalMatrixAuthorizationStrategy$DescriptorImpl.doCheckName

Fixed incorrect de-allocation of a classloader from the exported object
table.

The fix is a defense-in-depth; it prevents classloaders referenced in
the object graph from doubly released, then we also make it impossible
for bugs like this to deallocate the key classloader.
