Ignore warnings when running hg commands

hg may sometimes emit warnings that are not actually meaningful to the command being run by post-review.  For instance, my hg will emit the following for 'hg -q outgoing --template 'b:{branches}\nr:{rev}\n\n' when run with python2.5:
---
warning: certificate for foo can't be verified (Python too old)"
b:
r:8869
---

This warning is not meaningful, so we just ignore it.
Manual testing with a version of hg that gives this warning.
