Gerrit instances running at googlesource.com require authentication
with HTTP basic auth.
Add a new config option to allow to specify either basic auth or digest
auth. Default to digest auth if not specified.

Closes-Bug: 291
Add help text for the HTTP password option to all example configs,
since the issue is not obvious, especially give the current
failure mode of a traceback in JSON parsing code.
Add a direct link to the appropriate openstack setting page.

Update the openstack example config file with some additional help
text about the username and password. The first time I ran this it
took me a little bit to figure out the right password to use. I
didn't realize I needed to go generate a password in my gerrit
settings. Hopefully this note will avoid confusion by someone else in
the future.
