See here for notes.

Note

👉 First need to merge:

• Auto-read from user's configuration so no variables are required on deploy #32
• Allow non-string infra defaults for plugins covalent#1921

• The following infra defaults are not used for resource creation

client_id
client_secret
batch_account_url
storage_account_name
storage_account_domain
base_image_uri
pool_id

cache_dir
poll_freq

• tenand_id and subscription_id are no longer required
