EventFlow Core Library 1.1.10

This release improves the way errors are handled by the outputs

1. Failure to send data to its destination now results in a warning, instead of an error. This is because these errors might be transient, and it is also likely that the main service functionality is not affected, so a warning is more appropriate
2. TaskCanceledException is expected when pipeline is shutting down (e.g. because the whole service process is exiting) and is no longer reported as an error

Thanks to @Dineshwiz for pointing out these problems and helping with investigation

A simple error handling policy class was added to the core library and outputs have been modified to take advantage of it.
