feat(besadii): Add Sourcegraph index update triggers

Browse source 
Sourcegraph has a heuristic for determining when to update the
repository that doesn't work for the TVL repository, where commits are
often in irregular short bursts.

This changes besadii to trigger Sourcegraph index updates when invoked
by Gerrit.
