We have added gitea09 to haproxy which allows us to remove one of the
old servers. Remove gitea08 since gitea01 is the host that gets backups
currently.
Note that this only removes gitea08 from haproxy and does not remove it
from gerrit replication or our inventory. We need to do this in a
multistep process to avoid a situation where gitea08 is still serving
requests but not receiving updates from Gerrit. Next step will be to
disable replication. Then we can remove it from inventory and finally
delete it altogether.
