Some useful changes to the mysql node

[kuema]

Just a thought, but would using the tls-config config node be an option? It is already provided by the core.

Here's my previous post about that:

The TLS config node is provided by the core as tls-config, so you can use it like any other config node. So I think all you need to do is just add an optional node property, like tls: {type:"tls-config",required: false} The core MQTT node is a good example.
