Subject: [PATCH] [MNG-4343] maven always checks missing release artifacts
 [MNG-4592] Snapshot artifacts that could not be downloaded due to
 communication problems are "blacklisted" for a day by default.

o Allowed to configure caching of resolution errors in the execution request, thereby providing better control for CLI and IDE to select the desired behavior
