Add support for PCU operations

[emerkle826]

The DevOps API supports some new PCU operations that should be added to the provider's capabilities:

https://docs.datastax.com/en/astra-api-docs/_attachments/devops-api/index.html#tag/PCU/operation/pcuCreate
https://docs.datastax.com/en/astra-api-docs/_attachments/devops-api/index.html#tag/PCU/operation/pcuAssociationGet

It is likely that the astra-client-go will need these operations added first. The this provider can implement them for terraform use.

We have these PCU operation exposed via the https://docs.datastax.com/en/astra-api-docs/_attachments/devops-api/index.html#tag/PCUDevOpsAPI

To Implement this we would have to update the astra-client-go with the PCU API calls

then add this to this terraform provider

The goal here is going to be to add support for all operations currently exposed by the DevOps API as mentioned in the other comments: https://docs.datastax.com/en/astra-api-docs/_attachments/devops-api/index.html#tag/PCU

This includes:

• PCU CRUD
• DB associations actions
• PCU park/unpark actions

For some background on PCU groups generally check out the docs here: https://docs.datastax.com/en/astra-db-serverless/administration/provisioned-capacity-units.html

Are we surgically just updating the listed operations, or is it OK for us to wholesale bring the go client up to date with the latest devops api spec?

[jdonenine]

That's a good question... @emerkle826 from what you described I think the answer is that the Go client will always be updated with the full OpenAPI spec each time it's updated and generated, right? So I think that means wholesale bringing up to date.

[emerkle826]

Wholesale updating is fine. The client has to work with the DevOps API as deployed. However, if time is a concern, just bringing things up to date that are required for the PCU operations (for this ticket) is fine. Actually, it would be better to create a ticket for each of the endpoints that needs updating in https://github.com/datastax/astra-client-go to avoid a potentially large update all at once.
