'when: never' can only be used in conjunction with the 'rules' keyword [1],[2]
which in turn is mutually exclusive with 'only/except' [3] which we currently
utilize.

'when: manual' doesn't really feel like it's carrying the meaning properly.

I could live with ^this one accompanied by a commentary explaining clearly how
we intend to use it with regular jobs, but still it could cause some confusion
with other jobs where we have perfectly valid use case for using allow_failure
all the time.
With that in mind, I think what I'm proposing is much more verbose in what it's
trying to achieve and in itself it also kind of resembles the try-except
construct (only-except).
