v0.2.0

This release fixes a bug where certain exceptions in the Eventhub send methods would be silently dropped.

In addition, behavior has been added where for certain connection failures that occur while attempting to send an Eventhub message, the connection pool will expire those connections.

Lastly, the send methods formerly accepted a log= kwarg, but this was a holdover from a version of this library from before it was open-sourced where the expected logger would have been a custom logger. These log kwargs have been removed. Callers should confirm they're not including this keyword argument when calling methods on the Eventhub clients.
