Add existing bearer token support to Azure DNS API

[stbeldarborge]

The Azure DNS API only works with provided service principal credentials, or if running on a resource with a managed identity.
If you want to run it in a pre authenticated context (e.g. on a local machine which is already authenticated with az cli or in a GitHub Action which already has authenticated with azure/login), there's no way to do this.

This PR adds support to skip the authentication by providing the Bearer token.
With az cli the bearer token can be extracted and used in Azure DNS API with this command

export AZUREDNS_BEARERTOKEN=$(az account get-access-token --query accessToken --output tsv)

While #4981 is similar, these two are not the same, as #4981 does an authentication, while this PR supports authentication outside of the acme.sh context.

@Neilpang I've ran it through shfmt locally now, so hopefully it passes shfmt this time, if you can re run the workflows please

Now that all checks have passed, can you merge it @Neilpang ? :)

@Neilpang done!

Sorry, I did not understand the DNS API test documentation earlier, I thought I'd done it.
And I misunderstood some of the secrets, so that's why there are so many commits, because I had to debug what was happening.. You could squashmerge it 😅

@stbeldarborge Have you tested this with federated credentials on service principals + GitHub actions? I need to use acme with service principals keyless on github workflows. I'm about to test this but it might take a while.

Thanks for this PR!

Edit:
Just tried with federated credential and did work just fine.

[stbeldarborge]

absolutely, that's the exact usecase I have as well and the reason why I created this 😃 but would work with any context as long as it's authenticated to ARM

@Neilpang sorry to keep bothering you, but DNS API test succeeded, and it's in "production" even for others now like @maonat.. would be nice if it could get into the official release 👼

@Neilpang isn't this related to something else and not to the code that was implemented by @stbeldarborge? He simply merged master from this repo to his fork and that has nothing to do with his changes.

Edit: Check out... I've forked @stbeldarborge work on the commit before his latest master merge and got the following result:

The only error I get it from the DNS workflow because I'm getting an error for missing secrets (which is absolutely normal because I don't have those DNS secrets)

[EldarBorge]

@Neilpang like I mentioned, it does pass the DNS test; https://github.com/stbeldarborge/acme.sh/actions/runs/11272323811

However, you probably ran it without providing a token or a secret or any other authentication to Azure? If you ran the same workflow without authentication to Azure on master, that would fail too.

[Neilpang]

I didn't/couldnt' run the dns test , because I don't have Azure account.
what I meant was that the latest run in your fork was not success:
https://github.com/stbeldarborge/acme.sh/actions/runs/11287963136

please fix it.

[maonat]

@Neilpang Here I've ran the test on my repository I forked from @stbeldarborge repository.
Here is the completed and "all green" workflow
I cannot get in touch with them nor can make the run on their repository, would this test be ok for you?

[stbeldarborge]

@Neilpang latest run is green; https://github.com/stbeldarborge/acme.sh/actions

@maonat yeah, sorry, had other matters to attend to, but at least I've configured the secrets and re runned it now!

This should prove the code is good to merge hopefully? 🙏

[Neilpang]

would any of you guys update the usage here?

[stbeldarborge]

Absolutely! Updated the wiki now. 🙂

Done!
