Random small AAP things

This will be a place to gather all the little AAP things that I've found useful.

• rh-ah-token-refresh demonstrates automation of the renewal of your Red Hat Automation Hub Galaxy API token. I use this as a scheduled job in AAP, though it's made redundant by the remote_collections/sync_ah_remotes.yml below.
• remote_collections is an illustration of one possible way to create and sync your collection repositories and remote execution environment registries and EE images (from those remote registries) within Private Automation Hub.
• config_export contains a couple of playbooks to export the Automation Controller configuration in three different forms: one as a single YAML file, and the others as filetree (containing multiple YAML files). They may be illustrative for your configuration-as-code journey.

Where necessary, each of those contains a collections/requirements.yml showing the necessary collections. The README in each directory also contains information on dependencies, requirements, and usage.
