Initial pass at prometheus monitoring.
This is a step for #29118.
Add a single metric to count successful logins.
Summary types are not supported so remove Collector. Either
we need to support the summary type or we need to create a
multiprocess-friendly Collector.
Add config to load prometheus and set up the Collector and the
Exporter.
Fix `Gemfile` as current prometheus-client gemspec is missing the
`mmap2` dependency.
