Summary:
Now that we are writing the git hash inside the commit itself, if we are translating
from hg to git hash, we should just use that rather than loading the entire map and
build a dict and look it up.
The performance of this translation will also improve quite a lot.
Some small sample benchmarking:
```
suiting@devvm5006:configerator (659199b|remote/master)$ time ~/fbcode/scm/hg/hg log -r master -T '{node} || {gitnode}\n' --config exte
nsions.fbconduit=! --config extensions.hggit=
