lp-archive: add cache_max_size config to content-cache

The default is too high for the amount of disk space we currently use, so we set this value in production. The plan is to bump the disk space when possible, but while we don't, we should set a limit to prevent the units disk space to be completely used up

Auto-approving from the Launchpad reviewers side.
This is a trivial change that is already live in production.
