The previous repository default branch commit status cache will only
store if the commit status has value. So the repository which have no
any commit status will always be fetched from database.
This PR will store the empty state of commit status of a repository into
cache because the cache will be updated once there is a commit status
stored.
This PR adds a new table named commit status summary to reduce queries
from the commit status table. After this change, commit status summary
table will be used for the final result, commit status table will be for
details.

After repository commit status has been introduced on dashaboard, the
most top SQL comes from `GetLatestCommitStatusForPairs`.
This PR adds a cache for the repository's default branch's latest
combined commit status. When a new commit status updated, the cache will
be marked as invalid.
