Document configuring GCS/Azure snapshot repositories through the generic repository type.

[ezienecker]

The current docs for ec_snapshot_repository only include examples for configuring an S3 style repository. We should detail how to configure the generic repository type, including examples for Azure and GCS.

Original issue

---

Overview

ec_snapshot_repository currently only supports S3. It would be an advantage if the other cloud providers such as Azure were also supported.

Possible Implementation

resource "ec_snapshot_repository" "this" {
  name = "my-snapshot-repository" 
  azure = {
    container = "my-container"
  }
}

Testing

• Create snapshot repository.
• Change snapshot repository and verify it was changed.
• Delete snapshot repository.

Context

For migrations and backups I need to register in Elastic Cloud Repository.

@ezienecker the resource already supports a generic snapshot repository type. This comment can be used as an example of registering an Azure snapshot repository, but in general any both GCS and Azure repositories can be added through the generic block.

We need to improve the docs here with examples for GCS/Azure though, I'm updating this issue to make those doc improvements.
