Provider consistently flags changes in `avi_cloudconnectoruser`

[jakauppila]

Describe the bug

Whenever the avi_cloudconnectoruser resource includes a vcenter_credentials or nsxt_credentials block, Terraform repeatedly detects changes on each plan or apply run. Although the configuration remains unchanged, the plan output still indicates a removal and addition of the block, prompting unnecessary in-place updates.

I have attempted to add lifecycle to ignore some other values on the resource without success.

lifecycle {
    ignore_changes = [ private_key, public_key ]
  }

I'd assume the underlying issue may be related to #619; though what differs here is that the actual password is not obfuscated in state (which is what I would expect).

Reproduction steps

1. Include a avi_cloudconnectoruser resource in your Terraform configuration that defines a vcenter_credentials or nsxt_credentials block.
2. Run terraform apply to create the resource.
3. Execute terraform plan again without modifying the configuration.
4. Observe that Terraform flags the credentials block for an in-place update, even though no actual modifications were made.

terraform {
  required_providers {
    avi = {
      source  = "vmware/avi"
      version = "30.2.2"
    }
  }
}

provider "avi" {
  avi_username   = "USER"
  avi_password   = "PASSWORD"
  avi_controller = "avicontroller.contoso.com"
  avi_tenant     = "admin"
  avi_version    = "30.2.2"
}

resource "avi_cloudconnectoruser" "vcenter" {
  name        = "vcenter"
  vcenter_credentials {
    username = "VCENTER_USER"
    password = "VCENTER_PASSWORD"
  }
}

resource "avi_cloudconnectoruser" "nsx" {
  name        = "nsx"
  nsxt_credentials {
    username = "NSX_USER"
    password = "NSX_PASSWORD"
  }
}

Expected behavior

Terraform should only report a difference in the credentials block if there is an actual change in that configuration. If nothing has been altered, no in-place update should be triggered.

Additional context

Environment:

• Terraform v1.8.0
