Summary: Added config option 'prefetchdays' which indicates that commits older than 'prefetchdays' days should not be prefetched. This option is necessary to avoid prefetch of huge amount of data. The default value is set to 14 days. Test Plan: Ensure that unit tests pass Reviewers: ryanmce, simonfar, durham, #fbhgext, simpkins Reviewed By: #fbhgext, simpkins Subscribers: simpkins Differential Revision: https://phab.mercurial-scm.org/D420
