since it kept suggesting to add an import that is not needed nor used. If you add the import and then lint using .pylintrc, it then complains about the unused import.

What does this PR do?
It provides an alternative to
loop.untilthat does not useeval.Added example for using this in the faq. Made some pylint-inspired changes.
I'm not entirely sure that the name of the new state
until_no_evalis good enough (even though it is accurate), since it feels wrong to name a function with something that it does not have. I'm open to suggestions on this.What issues does this PR fix or reference?
None
Previous Behavior
The generic state that allows you to (blockingly) execute a salt function until it produces a desired output hinged on using
evalwith user-input. Since this is potentially very dangerous, an alternative has been supplied.New Behavior
A state exists (
loop.until_no_eval) that will block execution until a specific salt execution module function returns an expected result. This produced result is passed together with the expected result to a function (either a method of python'soperator, a function from__salt__or__utils__) to produce a boolean indicating success (or failure).Additionally, a parameter
init_waitis available to configure a waiting period before the 1st call of the salt function is made.Tests written?
Yes
