Add no_timeout and timeout options for calls

[lacraig2]

This PR adds no_timeout to copy_to_guest and record_cmd as well as timeout to record_cmd.

Adding timeout everywhere looks good, but do we really want to have an int and a bool option for all of these? I'd think we could instead just get rid of the no_timeout flag everywhere. Either way is fine with me though

@AndrewFasano That's a good point.

It looks like no_timeout only shows up in one place with run_serial_cmd. Removing it would break things currently using it.

We can certainly make these all take a timeout value.
