Added support for configuring terminal_storage_class in Autoclass

[Naveenchand06]

I have implemented the enhancement requested in Issue #395 by exposing the ability to configure the terminal_storage_class when Google Cloud Storage Autoclass is enabled

Previously, the module only exposed the enabled flag for Autoclass, defaulting the terminal storage class to NEARLINE with no option to override it. This update introduces a new variable, terminal_storage_class, allowing users to specify a custom value (example: ARCHIVE) per bucket. defaults to NEARLINE

autoclass {
  enabled = lookup(
    var.autoclass,
    lower(each.value),
    false,
  )
+  terminal_storage_class = lookup(
+    var.autoclass,
+    lower(each.value),
+    false,
+  ) ? lookup(var.terminal_storage_class, lower(each.value), "NEARLINE") : null
}

Add new variable

 variable "terminal_storage_class" {
   description = "Optional map of lowercase unprefixed bucket name => terminal storage class, defaults to NEARLINE."
   type        = map(string)
   default     = {}
 }
