Push

The constructor for the Push Manager has changed. (#5389)
- Push manager now takes only one argument, a Push Configuration object
- Push manager no longer takes in the registration_id (token) in construction
- Push manager now takes a new verifyConnectionRateLimiter parameter in its configuration, it defines the number of seconds between consecutive verify connection requests.
The update function no longer returns a boolean, the consumers did not use the return value. (#5389)
The Error exposed by push is now PushApiError, which is reduced to the set of errors the consumer is expected to handle. (#5389):
- PushApiError::UAIDNotRecognizedError: The server lost the client's uaid. The app should call verify_connection(true) and notify all consumers of push
- RecordNotFoundError: The record containing the private key cannot be found. The consumer should call verify_connection(true) and notify all consumers of push
- InternalError: Consumer should report the error, but ignore it

Changes handlePushMessage API so that it now returns exactly one event associated with the push message. (#5556)
- This API does not attempt to retrieve any missing tabs.
- Users of this API can use it to display the notification, but should use pollDeviceCommands after to capture the commands.
