CancelOnProcessTermination no longer enabled by default

[tmds]

Before #2044, the CancellationToken was hooked in the default configuration.

Now, you need to explicitly call CancelOnProcessTermination.

@adamsitnik is this an intentional change?

It's a bug, it's going to be fixed with #2107

where the timeout is going to have 2s value by default and the users will need to set it to null to disable the feature.
