fix: allow disabling field metadata cache (#1052)
Clients accessing very dynamic schemas can have issues with the
field metadata cache getting stale. This change allows configuring the
databaseMetadataCacheFields property to 0 to disable the cache and
avoid these issues where necessary. This behaviour was already
documented, however did not actually work as the codepath assumed
it could retrieve the fields from the cache.
**NOTE:** This service been marked for deprecation: https://developer.github.com/changes/2018-04-25-github-services-deprecation/
Functionality will be removed from GitHub.com on January 31st, 2019.
