Enable timeouts for command execution when using Hussh

[JacobCallahan]

Previosuly it was impossible to set command-level timeouts when using Hussh as the backend. In fact, due to the way the Host objects acquired their Hussh connections, timeouts were always left to the default. Now, with Hussh 0.1.7, we can pass a command-specific timeout.

Verified with hussh 0.1.7:
