Remove enable node watch setting as this can be enabled with an env variable

[johscheuer]

Description

I added a bit prematurely the new setting but the setting is actually not needed, so we should remove it. This will be a breaking change but since the feature is only relevant for the unified image, which is not yet released, I think it's okay to remove it.

Type of change

Please select one of the options below.

• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Are there any design details that you would like to discuss further?
