  This class allows you to interact with OWNERS files in a repository both the

  Depot Tools in owners.py:

   - List all the owners for a change.
   - Check if a change has been approved.
   - Check if the OWNERS configuration in a change is valid.

Add owners client to depot_tools.
[depot_tools][owners] Add owners client to depot_tools.

Add an owners API that will be used by Depot Tools to
interact with OWNERS files.

The API will be implemented using both owners.py and the
Gerrit Code-Owners plugin REST API. All Depot Tools code
will be modified to use this API.
