Allow variables in `ignore_error`

[skuroyama-AoPS]

Description

Hello! I'd like to ignore errors on a watch-like process. Whether a process is watch-like is determined by a variable passed in, .WATCH. However, ignore_error only takes a boolean. Is it possible to have that field be able to evaluate variables?

@skuroyama-AoPS you could try this method/workaround:

some_cmd || true

...which can then be adapted with templates (e.g. appending the '|| true' part) to be evaluated as you wish.

A bit clunky, but that works for my use case. Still better than having an entire extra helper to separate things out. Thank you!
