rust getting started

[olivakar]

First rust sample for basic getting started scenario

Great PR !! just a few nits:

1. Solve branch conflicts
2. Add cargo.toml at the root
3. Refactor getting started to move common code (like TLS) to mqttclients

[olivakar]

Adding cargo.toml at the root does not work with the existing cargo commands. So for now I am not doing that. Any cargo file needs to be tied to the rest of the cargo files.

sure, and the cargo.tom at the root should reference all the other cargo.toml

Can you try to find a sample on how to do it correctly?

@andyk-ms I saw you approved the PR without my suggestions to refactor the TLS code into the mqttclients lib.

Do you want to get this merged now and do the refactor later?

I'd prefer to complete this PR with the proper helper methods to avoid the code duplication we have in Python.
