Need resource types to edit boot source, and manage its boot resources based on selection. Functionality to import images from a selected boot source is also missing.

It would be helpful to have a MAAS Terraform provider implementation for, at least, the following operations/commands:

maas $PROFILE boot-source update $SOURCE_ID url=$URL keyring_filename=$KEYRING_FILE

Importing newly selected images for the boot source
maas $PROFILE boot-resources import
