Adding ifAllowed method to policy

[Thai Tran]

Policy current returns a response object containing the allowed field, which either is true or false. To simplify this a bit, we need a wrapper method ifAllowed that would return a promise that either resolves or rejects. If it resolves, the success handler is called, and if it rejects, the error handler is called. This is more useful in practice and negates the need to check the response object. Furthermore, this is useful for creating a hz-if-policies directive in the future.

    Adding ifAllowed method to policy service

    Policy current returns a response object containing the allowed field,
    which either is true or false. To simplify this a bit, we need a wrapper
    method ifAllowed that would return a promise that either resolves or
    rejects. If it resolves, the success handler is called, and if it rejects, the error
    handler is called.

    This is more useful in practice and negates the need to check the response
    object. Furthermore, this is useful for creating a hz-if-policies directive in
    the future. The user table controller is included in this patch to show how it
    can be use in practice.
