INTMDB-198: Fixes a bug where it appears empty private endpoint in cluster

[coderGo93]

Description

• Added a refresh state for cluster when it can wait for private endpoint to be available if will be used if the provider name is AWS or AZURE with 10 minutes as timeout in datasource of cluster.

This was tested manually because in issue, was using an existing cluster with datasource.

The example is the same in folder /examples/aws-atlas-privatelink with small modifications in file atlas-cluster.tf like this

data "mongodbatlas_cluster" "cluster-atlas" {
  project_id                   = var.atlasprojectid
  name                         = "cluster-atlas"
  depends_on                   = [mongodbatlas_private_endpoint_interface_link.atlaseplink]
}

output "atlasclusterstring" {
  value = data.mongodbatlas_cluster.cluster-atlas.connection_strings
}
output "plstring" {
  value = lookup(data.mongodbatlas_cluster.cluster-atlas.connection_strings[0].aws_private_link_srv, aws_vpc_endpoint.ptfe_service.id)
}

The results are OK after waiting for data.mongodbatlas_cluster.cluster-atlas, it took between 3-5 min

@threebee I added you since the APIx group added Andrea who is OOO. Hope this is okay! If not feel free to reassign.

LGTM!

[threebee]

LGTM!

@coderGo93 I talked with Chris who works with private link quite a bit and he feels Azure should be given the same amount of time. Can we do this for both providers?

[coderGo93]

Hi @themantissa , just updated validation so it can be refreshed if the provider is azure or aws

[thetonymaster]

LGTM
