validateClient() : bool
This method is called to validate a client’s credentials.
The client secret may or may not be provided depending on the request sent by the client. If the client is confidential (i.e. is capable of securely storing a secret) then the secret must be validated.
You can use the grant type to determine if the client is permitted to use the grant type.
If the client’s credentials are validated you should return true, otherwise return false.
