Setup Ansible playbooks for staging environments

[robe]

I setup a staging environment under ansible playbook which I used to test out the wiki -> LDAP migration.

The staging environments I also need to resetup from a snapshot of production and make configuration changes e.g. change the domain from

x.osgeo.org to staging.x.osgeo.org

These playbooks will be used to copy a snapshot from production env, restore on osgeo4 (eventually OSM servers too), as <container-name>-staging, make respective apache/nginx setting changes for the new domain.

This will be useful for testing out major upgrades like os upgrades or major application upgrades (like we'll need to do for tracsvn, nextcloud and wordpress soon).

I'm going to start with wiki-staging

and then tracsvn

Move these to next contract milestone

Already done wiki-staging, tracsvn-dev, nextcloud-dev, old-web-staging. Still need to do for secure-dev.

Ticket retargeted after milestone closed

Ticket retargeted after milestone closed

going to close this out and create separate ones for each that needs it.

So for we have

wordpress-dev #stationery, not reloaded since it holds staging and dev. wiki-staging, tracsvn-dev, nextcloud-dev, ldap-web-staging, pretalx-staging (this turned off and turn on as needed)
