Nest command unhandled error process exit 1 (#20312)

# Introduction
When running the `run-instance-commands` on a migration failure the
process wouldn't throw at all
Leading to conditional flow to keep going whereas it should have stopped
This update is very invasive and impacts all the nest commander
registered commands
We should keep in mind that it impacts the way we create and init
database and so on

But I think that's for the best, as cli that never exit 1 is
counterintuitive
