Storage sizes can now be configured.
Due to limitations of yaml/load-as-edn volumes.yaml was
split into datavolume.yaml and rootvolume.yaml. This
way, we are able to follow volume size recommendations
described in jira.
Valid config was updated. Tests were updated.
We now have a basic config for our gitea installation.
We might want to have a closer look on the security config.
Also updated tests and gitea.cljc code with params and formating.
