Add JWT options for acl_auth_method

[jorgemarey]

Fixes #422

Thanks for the PR @jorgemarey!

Have you tested what happens if type changes? Would we leave an orphaned auth method in Nomad? Maybe we would need to update it to have ForceNew: true?

I was also wondering if we should validate config based on type, but I don't think we can do cross-field validation at plan time, at which point we may as well let Nomad knows if something is wrong on apply.

Would you also be able to add a CHANGELOG entry and update the website docs?

Thanks!

Hi @lgfa29

Have you tested what happens if type changes? Would we leave an orphaned auth method in Nomad? Maybe we would need to update it to have ForceNew: true?

I didn't notice this, but I just tested and the method seems to change correctly in nomad. So I guess there's no need to set ForceNew to true then.

I was also wondering if we should validate config based on type, but I don't think we can do cross-field validation at plan time, at which point we may as well let Nomad knows if something is wrong on apply.

I don't know how to do this. I you think we can do something on plan time let me know and I'll make the change.

Would you also be able to add a CHANGELOG entry and update the website docs?

Done!
