Print progress, print status, print health emails are not being received

[leigh-johnson]

Describe the bug

Original report:

I turned on all notifications in the cloud and have yet to receive any communication from printnanny (start, stop, cancel, progress, issues, etc).

[leigh-johnson]

I'm digging into this today, and found a TLS version mismatch between websocket clients and the cloud NATS server. This would impact cloud browser notifications (not emails), but going to fix this while in the neighborhood.

:+1: Fixed the transformation of OctoPrint printer status events into NATS messages.
