feat: Add uninstall tag and rename cleanup flags

[nahsi]

When playbook is run with --tags uninstall ansible will stop and disable services installed by role (prometheus in prometheus role, nox in nox role etc), delete directories with state and config and stop. So it can be used to permanently delete everything fluence on the server.

There is also a fluence_cleanup flag that will stop nox and ccp, delete state and start them again.
nox and ccp roles also have a separate flags nox_cleanup and ccp_cleanup.
nox_cleanup_state and ccp_cleanup_state also work.
