Feature Request: Configurable timeout for mlagents-learn to connect to the Unity editor

[JesseTG]

Is your feature request related to a problem? Please describe. Unity takes a long time to start Play Mode, which is an issue in itself but not one in this project's scope. If I start Play Mode and mlagents-learn at the same time, mlagents-learn might time out before the training environment is ready.

Describe the solution you'd like A command-line option that lets me decide how long I want mlagents-learn to wait for an editor (or player) connection before timing out.

Describe alternatives you've considered Optimizing my training environment's startup. I intend to do this, but in the meantime this feature would simplify my life. Currently I wait a few seconds after clicking the Play Mode button before I start mlagents-learn.

EDIT: Another workaround is to insert a sleep command before mlagents-learn. On PowerShell, that would be...

Start-Sleep -Seconds 60 ; mlagents-learn

...however, this workaround still involves an element of manual timing.
