Instead of using comments declare info in a special variable.
Then the variable can be used to print the DNS API provider usage.
The usage can be parsed on UI and show all needed inputs for options.
The info is stored in plain string that it's both human-readable and easy to parse:
dns_example_info='API name
An extended description.
Multiline.
Domains: list of alternative domains to find
Site: the dns provider website e.g. example.com
Docs: Link to ACME.sh wiki for the provider
Options:
VARIABLE1 Title for the option1.
VARIABLE2 Title for the option2. Default "default value".
VARIABLE3 Title for the option3. Description to show on UI. Optional.
Issues: Link to a support ticket on https://github.com/acmesh-official/acme.sh

Here:
VARIABLE1 will be required.
VARIABLE2 will be required too but will be populated with a "default value".
VARIABLE3 is optional and can be empty.
A DNS provider may have alternative options like CloudFlare may use API KEY or API Token.
You can use a second section OptionsAlt: section.
Some providers may have alternative names or domains e.g. Aliyun and AlibabaCloud.
Add them to Domains: section.

The function '_get_root' tries to retrieve the
hostedzone iterating the domains, eg:
1. srv.prod.example.com
2. prod.example.com
3. example.com
This doesn't work if '_acme-challenge' is in it's
own hostedzone for security reasons.
Starting that iteration with '_acme-challenge.srv.prod.example.com'
fixes this issue.
This is to provide a clean path to future extension work such as adding
a _use_container_role function to offer similar support for ECS
containers.
The $_using_role flag has also been made generic so that future role
providers can also make use of it.
Use the behavior established in the botocore python library to inform
how and when instance metadata is fetched in an attempt to acquire valid
AWS credentials.
- Use it as a fallback when no other credentials are provided
- Set the timeout of metadata requests to 1 second
Add option (AWS_USE_INSTANCE_ROLE) to have the AWS DNS API driver pull
the necessary credentials from the AWS EC2 instance metadata endpoint
when required.
This is a non-breaking change as it only takes effect when explicitly
turned on via the environment variable, and fails safe back to the
normal code path.
