[Feature Request]`Include` Syntax Support

[jiz4oh]

Hi, thank you for creating so awesome plugin.

The ssh config supports Include syntax from 7.3p1, could you mind adding this syntax so that I can search it in Neo-Tree

That's an interesting idea! I did not know about that feature of ssh_config.

I have been wanting to update the ssh provider to better support stuff like dynamic endpoints, saving new connections without needing the ssh config, etc.

This seems like a fantastic addition to it. I have heavily slowed down development of Netman simply due to time constraints but I do like this idea and I don't imagine it will be "too difficult" to implement.

Alternatively, if you are feeling spicey, I have no issue in helping guide you through how to add something like this to the ssh provider
