Refactoring with ansible lint tag resources

[cppmonkey]

Refactored a few areas where more appropriate modules were available.

Looks to be an issue with these sections, as they both reference the same file

tasks/geoserver.yml

• name: patch the geonode-oauth file (geonode part)
• name: patch the geonode-oauth file (geoserver part)

Tested with the following command.

$ ansible-lint -t resources geonode-v2.yml
