Enable terminal storage class option along with auto class

[rabollam]

TL;DR

Currently in the module we are only enabling auto class and by default google sets terminal storage class as NEARLINE.
if we have an use case to change this to ARCHIVED this module doesn't have this feature to set, Hence I am requesting to enable this feature.
please note terminal storge class works in conjunction with auto class and it is already available in terraform resource block terminal_storage_class
