Based on recent usage stats. If these are not set, the scheduler's
capacity check doesn't work and it will place new pods on nodes that are
actually not free enough for them.
This includes all the resources currently running on https://gitea.kosmos.org
It sets up a persistent data volume for the MySQL database, one for the
Gitea data, that Gitea calls the custom folder (config, attachment,
avatars, logs, etc). We mount that persistent data volume as
/data/gitea. It also creates a Let's Encrypt certificate for
gitea.kosmos.org, also saved to the custom folder.
This also includes two scripts:
* `./script/get_secrets` downloads the secrets to the local filesystem so
they can be edited
* `./script/replace_secrets` deletes the remote secrets and creates them
again from the local ones in kubernetes/config/*
