Sean McGinnis 1729c889c2 Base framework for cinder-status upgrade check

This adds the cinder-status CLI for performing upgrade checks as part of
the Stein cycle upgrade-checkers goal. It only includes a placeholder
for actual checks. Follow up patches will need to be added for anything
we identify as needing specific checking.

Upgrade

cinder-status upgrade check

Return Codes

Return code	Description
0	All upgrade readiness checks passed successfully and there is nothing to do.
1	At least one check encountered an issue and requires further investigation. This is considered a warning but the upgrade may be OK.
2	There was an upgrade status check failure that needs to be investigated. This should be considered something that stops an upgrade.
255	An unexpected error occurred.
