add javadocs to some abstract methods on MdmCommand.  add deprecated tags to old parsing paths we're already in the process of phasing out to highlight the work to do.
remove last vestiges of args parser in constructors from MdmReleaseCommand and MdmReleaseInitCommand.  (...wow, deprecation flags are darn handy for directing updates to your own source.)
cleanup unused imports
start laying out test infrastructure for the add command.
tease apart some of the args parser references in MdmAddCommand.
pull the version arg in MdmAddCommand out to parse function
reorder add command prompts and other checks (check url before prompting for name, but local filesystem check also has to follow name prompt).
remove the args parser constructor arg from MdmAddCommand.  hooray, deprecation reduce!
switch the visibility of MdmAddCommand component methods to default for future test access, and let them use more config state now kept in the command instance.
more breakdown of MdmAddCommand into small functions.
