[BUG] salt.utils.versions.warn_until doesn't seem to be warn-ing

[nicholasmhughes]

Description
DeprecationWarning is being filtered somewhere...

Inserting a block like this into a function doesn't actually throw the warning (I tested by inserting it into test.ping):

    salt.utils.versions.warn_until(
        "Chlorine",
        "message here",
    )

but this block does throw the warning properly:

    salt.utils.versions.warn_until(
        "Chlorine",
        "message here",
        category=FutureWarning,
    )

The salt.utils.versions.warn_until function defaults to using the DeprecationWarning class. Changing the category argument to another class, such as Warning or FutureWarning, allows the warning to be shown as expected.

There are filters in place in a couple of places in the code, but I couldn't narrow down where it was being suppressed.

This is problematic, because users aren't being shown deprecation warnings as expected... so removal of functionality may come as a surprise.

@s0undt3ch any ideas here?

I can confirm this. Here is a simple reproducer: #59917 (comment)

Just ran a git bisect. Not sure why, but fe075aa is apparently where it started going sideways 😕

Hrm... that may be because I didn't have distro installed. Let's try that again...

24d503a looks like it
