The default indexer timeout is 30 seconds. During a recent gitea restart
gitea01 hit this timeout five times: 150 seconds. Increase the timeout
to double that value: 300 seconds.
This is important to ensure that our graceful restarts are in fact
graceful. We don't want the sshd container running while web is being
restarted multiple times. Doing so can lead to lost replication events
from gerrit.
