Merge ~pwlars/revcache/+git/revcache-charm:fix-config-defaults into ~canonical-hw-cert/revcache/+git/revcache-charm:master

[Paul Larson]

Fixes some bad defaults (which are easy to work around, but better to have the right defaults). Also, I think that having the config file written at config-changed time *might* be better. It's hard to test, because even at relation-changed time, it's kind of bad right now. Juju doesn't always fill in the variables the way it's supposed to.

[Paul Larson (pwlars)]

I'm iterating on these minor fixes right now, would like to go ahead and land/deploy this
