2019-05-16 1.0.0

• receiveMessages() now returns rejected promise when network connection is lost.
• Receiving messages from a session whose id is an empty string is now allowed.
• Errors thrown explicitly by the library for the user facing apis are documented in jsdocs.

Breaking changes

• When Service Bus does not acknowledge a message settlement/disposition request in time, the error
  ServiceUnavailbleError is thrown. This is consistent with send requests and requests over the $management link.
• The error MessageLockLostError or SessionLockLostError (based on whether the entity has sessions enabled
  or not) is thrown for a message settlement/disposition request when the AMQP receiver link that was used to receive
  the message has died.
• User agent string which is passed as a AMQP connection property is updated to follow the new standard.
