[Feature Request]: Remove region parameter on issuer

[tdaniely-dn]

Describe why this change is needed

The region field on AWSPCA Issuers is redundent and only allows breaking the issuer.

I might have it wrong but it seems that the region must always match the region of the specified PCA arn.
Any region value that is not the region from the PCA arn, will always break.

Therefore it seems that having the parameter at all is a bug, as it's only function is to allow the user to break the issuer.

Describe solutions and alternatives considered (optional)

Controller should derive the API client region from the CA arn itself.

Is there anything else you would like to add?

Thank you for the very usefull tooling!!

Thank you for submitting the feature request to AWS Private CA Issue plugin. We will review the request to verify potential usages of the region field and scope out necessary code changes, and get back to you.

We reviewed the feature submission, and we agree that there is redundancy as you identified. The region field on AWSPCA Issuers doesn't break core functionality, so we are unable to prioritize implementing this feature at the moment. However, we are happy to review any PRs for this feature, so we will leave this feature request open.
