Mirror memcached:latest from docker hub to quay.io/opendevmirror

We are looking at using memcached to back Gitea's caches. To integrate
that with our existing docker-compose setup for Gitea it would be nice
to run memcached from a container too. Unfortunately, we've had problems
with docker hub rate limits so mirror this image to
quay.io/opendevmirror before we start to use it.
