restart-dbc missing

[Nicolaie Marian]

@wmudge : Restart CDW dbc is missing. Will do a PR. Will add as well the correspondent Ansible module code in the Ansible cloudera.cloud repo.

@nmarian85 - I've started working on a general DBC module for cdpy, see #56

[Dan Chaffelson]

@wmudge do we still need this open?

[Webster Mudge]

No, I think we can close and work on the DBC module mentioned in #56 .
