Add capability to attach multiple values for same category key to pc entities

[bhati-pradeep]

Is your feature request related to a problem? Please describe. Yes. Currently we can only add one category value for one key to an entity. There should be ability to add multiple values to same categories for an entity. For example, adding Environment -> Dev and Production category key values to vm.

Describe the solution you'd like In API, we can use "categories_mapping" field which allows same operation.
