1149007: Fixed subman command line usage

- The following options have been deprecated and replaced by
  hypenated alternatives:
  - serverurl
  - proxyuser
  - proxypassword
  - activationkey
  - consumerid
  - servicelevel
  - listslots
  - listhooks
  - ondate

  The original non-hypenated versions still work and should forward
  to the new versions, but will print a deprecation warning to stderr.

  This also addresses bz 1154179 for hypenating all command line
  options.

- Subscribe and unsubscribe now print deprecation warnings to
  stderr when used.

- Tab completion for subscribe, unsubscribe and all deprecated
  CLI options has been removed.
