Adding a location

Feature description

Locations are not directly added with mutations, but rather when anything related to that location is created.

For example, if I create a heist on a location (that is not in the DB), it needs to be added to the DB.

However, we need to check beforehand if the location exists and is valid (from the Google Maps API).

• Add a validator to check that the location does exist and is located in New York City.
• Don't enable direct mutations.
• Add tests for validating the location.
• A location should be represented by its latitude and longitude properties (API identifier).
