Subject: [PATCH] Set docker volumes to cache consistency mode (#4838)

(Only applies to OS X)

boulder is, typically, not a long lived docker container, and we don't
really care about synchronous consistency between the host fs and
container fs. cached provides the best performance for read-heavy
workloads, which is what is typically slowest on container startup
(at least from my experience).

This change provides a 30-40% speedup on OS X.
