Add support for managing Members

[niels-s]

Is your feature request related to a problem? Please describe.

We would like to be able to manage inviting members and their permission groups. The public API exposes the necessary endpoints for it: https://configcat.com/docs/api/reference/members/

Describe the solution you'd like

We expect a new TF resource to be implemented so we can manage members of our organization.

Hello @niels-s ,

Thanks for reaching out.
Unfortunately, our Public Management API currenty does not support all the member related management endpoints (e.g. you cannot manage organization admins/billing managers with the Public Management API).
Also, we have plans to improve our invite flow too as currently you can only invite a member to 1 product, but it would be much better if you could invite to multiple products. We have plans to improve on both of these.

After that it seems to be a real good thing to add these functionality to the Terraform provider as well.
We don't have an ETA for these changes. I created a ticket on our backlog so we can notify you if we made any changes.

Have a great day!
