dashboard/app: poll commits info

This implements 2 features:
 - syz-ci polls a set of additional repos to discover fixing commits sooner
   (e.g. it can now discover a fixing commit in netfilter tree before
   it reaches any of the tested trees).
 - syz-ci uploads info about commits to dashboard.
   For example, a user marks a bug as fixed by commit "foo: bar".
   syz-ci will find this commit in the main namespace repo
   and upload commmit hash/date/author to dashboard. This in turn
   allows to show links to fixing commits.

Fixes #691
Fixes #610
