Throw Exceptions for certain HTTP responses

[jimmyz]

The client should throw exceptions on the following HTTP responses:

• 401 - Unauthorized
• 403 - Forbidden
• 404 - Not found
• 405 - Method not allowed
• 406 - Not Acceptable
• 409 - Conflict
• 410 - Gone
• 415 - Unsupported Media Type
• 429 - Throttled
• 500 - Internal Server Error
• 502 - Bad Gateway
• 503 - Service Unavailable
• 504 - Gateway Timeout

The exceptions should fall within the Gedcomx\Rs\Client\Exception namespace. The exceptions should contain the HTTP response, the code, and the server message.

I approve.

We're going to implement this as an option in the FamilySearch client, if possible.
