upgrade staging to latest stable release

[gubuntu]

GeoNode 2.8
stable GeoSAFE
stable QGIS server etc.

ensure the documentation and Rancher catalog is clear to follow for doing a staging release

then deploy to production on geonode.kartoza.com when approved.

[gubuntu]

@boney-bun please do this

deploy staging onto geonode.kartoza.com, keeping all the content on that server. Configure it to accept staging.geonode.kartoza.com as well.

Then we will close down the old staging server

[gubuntu]

Also configure it to accept geosafe.kartoza.com

And it must have the generic theme (not INGC)

staging.geonode.kartoza.com DNS is now pointing to the geonode.kartoza.com host (from today)

[gubuntu]

@lucernae please complete this before the Hetzner switch next week. cc @AndreLester

To summarise:

• ensure the geonode.kartoza.com host accepts staging.geonode.kartoza.com and geosafe.kartoza.com (it doesn't accept either atm)
• ensure geonode.kartoza.com is running the latest stable version, with the generic theme, not INGC. Or, better still, a Kartoza theme.
