Gitea deployment, now Ansible based

FYI, the Gitea configuration is now controlled via ansible.

Staging deploy:

  ANSIBLE_CONFIG=ansible.osgeo.staging.cfg \
  ansible-playbook deployment/deploy-gitea.yml

Production deploy:

  ANSIBLE_CONFIG=ansible.osgeo.staging.cfg \
  ansible-playbook deployment/deploy-gitea.yml

The configuration is now a template:

  deployment/roles/gitea/templates/app.ini.j2

This allows us to use variables to tweak the configuration
for use in staging, as done by the staging inventory group
var file:

  inventory/staging/group_vars/gitea.yml

For this reason the gitea-config git repository was archived
and remotes for it were removed from the production and
the staging server.

The wiki page was updated accordingly:

  SAC:Gitea - OSGeo
