This CL makes a couple changes:
* The goal here is to be able to specify git cache entirely from the
environment variable $GIT_CACHE_PATH and not require special treatment from
bot_update. Eventually this will be specified at the swarming task level
instead of in the recipe (i.e. "cached git" will eventually be an
implementation detail of git on the bots and completely transparent to
all other software).
* Removal of the general --cache-dir option from gclient. This option was
error-prone; it doesn't actually make sense to configure this on
a per-invocation basis. The sole exception was `gclient config`, which
now allows this option to be set directly.
* Consolidation of GitWrapper.cache_dir and GitWrapper._GetMirror; previously
these two things could disagree, leading to weird intermediate states. Now
they're the same value.

With this change, 'git cache fetch' will automatically re-bootstrap
a repo from google storage if the local cache has too many pack
files. The behavior can be disabled with the --no-bootstrap flag.
