Caching

This release introduces metrics caching to reduce the amount of unnecessary calls to the Borg repos, especially remote ones.
Use the BORGMATIC_EXPORTER_CACHE_TIMEOUT environment variable to set cache expiration, the default is 10 minutes. Caching can be disabled completely by setting the value to 0.
