RFR: 8239026: Support non-maven artifacts by JibArtifactManager

[Leonid Mesnik]

Hi

Could you please review following fix which extend JibArtifactManager to support download and installation of artifacts with layout different from maven style. 
It is planned that user provide name and properties to resolve layout using default or jib manager. There are no tests which use this customization  currently added in the testbase. So there is no good interface like Artifact annotation is added.
