turn 'edit variables' into environment variables

[jvanasco]

i'd be willing to write a PR for this.

This way the file can just be synced against the upstream source as needed, and customization would be via...

export ACMEDNSAUTH_ACMEDNS_URL=string
export ACMEDNSAUTH_STORAGE_PATH=string 
export ACMEDNSAUTH_ALLOW_FROM=json encoded string
export ACMEDNSAUTH_STORAGE_PATH=String Bool (1/True) or (0/False)

This is a really good idea, and I'm looking forward for your PR!

[leggewie]

This indeed sounds great.

@jvanasco any progress?

[jvanasco]

the PR is stale by several years. You are welcome to rebase and resubmit. I will not have time to address this in the near future
