This change introduces a Zuul gate that deploys a limited number of
components from the Airskiff site (i.e. memcached) using the Airskiff
site documents. The purpose of the job is to gate all patches against
an integration of several Airship components (i.e. Armada, Deckhand,
Pegleg, and Shipyard), and exercise their capabilities by deploying
software. This change also creates a framework to allow for future,
robust gates that include other projects (e.g. OpenStack-Helm).
