Changes in CLI arguments between versions

[DonJayamanne]

Environment data

• PTVSD version: 4.1.3
• Using VS Code or Visual Studio: N/A

Actual behavior

• CLI args for starting apps for remote debugging has changed
• Now the arg requires --server-host, this wasn't the case in the past.
• This is a breaking change.

Expected behavior

• We need to revert if possible as existing users will not be able to use PTSVD for remote debugging scenarios.

Please feel free to change the Priority label.

FWIW I think the --server-host came in on the previous version? I could not get remote debugging working with 2018.8.0 / 4.1.2, and specifically waited for these combination of versions to work again, so please don't just revert if you can manage it.

so please don't just revert if you can manage it.

No decision had been made yet.

Sorry, I realised that, just providing a bit of extra context. I'm super excited to have remote debugging for django in docker!

I've tried debugging with the master branch of PTVSD using the following args:
python -m ptvsd --port 5678 sample.py

It doesn't seem to work.
I.e. I cannot seem to connect to the remote machine. I need to add --server-host 0.0.0.0 to get it working.

Verify using this branch v4.1.4-branch

Oops, tested there too, no luck.
Have to use --host 0.0.0.0 for it to work.
