BUG - Service Template - AKS Template plan always calculates 1 change

After the Software Upgrades from Issue #75 (closed) the plan for Service Resources always calculates a Diagnostic Change due to a new implementation of diagnostic settings.

  # azurerm_monitor_diagnostic_setting.aks_diagnostics will be updated in-place
  ~ resource "azurerm_monitor_diagnostic_setting" "aks_diagnostics" {
        id                         = "/subscriptions/929e9ae0-7bb1-4563-a200-9863fe27cae4/resourcegroups/osdu-mvp-srscholl-0uq8-rg/providers/Microsoft.ContainerService/managedClusters/osdu-mvp-srscholl-0uq8-aks|aks_diagnostics"
        name                       = "aks_diagnostics"
        # (2 unchanged attributes hidden)


      - metric {
          - category = "API Server (PREVIEW)" -> null
          - enabled  = true -> null

          - retention_policy {
              - days    = 100 -> null
              - enabled = true -> null
            }
        }
      + metric {
          + category = "AllMetrics"
          + enabled  = true

          + retention_policy {
              + days    = 100
              + enabled = true
            }
        }
        # (7 unchanged blocks hidden)
    }

Plan: 0 to add, 1 to change, 0 to destroy.
