[paho-dev] Started a Rust client

[Frank Pagliughi <fpagliughi@xxxxxxxxxxxxxx>]

Hello All,

I've started a Rust language client library for MQTT. It wraps the Paho 
C library (for Windows/Linux), so should have some complete 
functionality in a short amount of time. My plan is to target the 
existing Paho release, so as to have MQTT 3.1 compatibility out of the 
gate, and then track the updates to v5 with the rest of the libraries.

So far I have some basic capabilities implemented for connecting and 
publishing messages, but it's coming together pretty quickly. I can get 
a get a page on the Eclipse GitHub site and start uploading code if 
people are interested.

Thanks,
Frank Pagliughi
