[326] Added The exclamation point to input type field for CustomerAddressInput schema

[RickyThakur]

Description (*)

The exclamation point ( "!" , field value can not be null, required field ) missing from the customer's mutation input type object arguments for the input CustomerAddressInput .

1. GraphQl uses '!' mark to promise that field can not return null value OR field is required

2. In graphql-ce/app/code/Magento/CustomerGraphQl/etc/schema.graphqls the CustomerAddressInput has following required fields

   city: String
country_id: CountryCodeEnum
firstname: String
lastname: String
street: [String]
telephone: String

3. Error response for validation for CustomerAddressInputInput is being thrown by GraphQlInputException from resolver

"message": "Required parameters are missing: city, country_id, firstname, lastname, street, telephone",
 "category": "graphql-input",
  ......

There should be '!' sign after the datatype declaration according to GraphQl syntax.

 `city: String!`
 `country_id: CountryCodeEnum!`

Fixed Issues (if relevant)

1. Fix for wrong coupon calculation. magento2#326: The exclamation point ( "!" , field value can not be null, required field ) missing from the customer's mutation input type object arguments for the input CustomerAddressInput
