Title: ServiceBus: Implement Renew-Lock for Message

Source documentation on MSDN: [Renew-Lock for Message from Queue (Non-Destructive Read)](http://msdn.microsoft.com/en-us/library/jj839741.aspx).
Style and test coverage are largely taken from the "UnlockMessage" function implementation.
Tests pass OK against a real Azure service bus (with NOCK_OFF="true"); I guess it won't be helpful to commit my own NOCK recordings for the case.
CLA signed and emailed.
