Add rootless support for geonode

[cmotadev]

Add rootless support for geonode django/celery, in addition to this pull request: rootless geonode docker.

Objectives

• Make geonode (django/celery) to run rootless
• Apply some Dockerfile best practices, to reduce image size and number of layers
• Evict to make deeper modifications, like change libraries (except the use of curl and wget - in this case we removed wget and changed to curl)
