…ve and on CustomerAddressInput via @doc

Description (*)

I've added the required deprecated directive to CustomerAddress and CustomerAddress(via @doc).

Manual testing scenarios (*)

1. Access graphql using either the chromeiQl or any other graphql IDE.
2. Open documentation tabs and search for CustomerAddress and under Deprecated fields you shoud able to see the custom_attributes field ant a the reason for the deprecation notice.
3. Search for CustomerAddressInput under documentation and the custom_attributes will have a deprecated notice on its description

Questions or comments

Since the custom_attributes field was not present on any of the web api tests there was no reason to change any of those files responsible for testing the CustomerGraphql module.
