Title: (PUP-2702) Change to unlimited caching as the default

The most effective and safe caching strategy for environments is
"unlimited" since it gives the user control over the resource utiliztion of
the master, provides a clear deployment point, and allows the master to pick
up any ruby code changes that are part of the new environment code.
