Make raw imports from _utils work

[mephi42]

This is a quick hack to make it work with salt-ssh.
It would be great if anyone could outline the proper solution, since I got lost in module loading logic.

What issues does this PR fix or reference?

#32500

Previous Behavior

Importing _utils module resulted in ImportError.

New Behavior

Importing _utils module works as described in https://docs.saltstack.com/en/latest/topics/utils/index.html

Tests written?

No

Commits signed with GPG?

Yes

This would not be a good idea, it would add utils functions to both __salt__ and __states__.

Can you show an example of what you're trying to do, what you expect to happen, and what is happening instead? Your most recent comment in the linked issue doesn't really offer much information.

I'm trying to make the following example from the doc work:

_utils/mymodule.py:

class Foo(object):
    def bar(self):
        return 'baz'

_modules/awesome.py:

import mymodule
def observe_the_awesomeness():
    foo = mymodule.Foo()
    return foo.bar()

In v2017.7.3 it fails with an ImportError.

OK, I'm not familiar with this functionality, I will investigate.

I see now what you meant in your comment:

[ERROR   ] Module/package collision: '<redacted>/lib/python2.7/site-packages/salt/utils/docker' and '<redacted>/lib/python2.7/site-packages/salt/states/docker.py'
[ERROR   ] Module/package collision: '<redacted>/lib/python2.7/site-packages/salt/utils/pkg' and '<redacted>/lib/python2.7/site-packages/salt/states/pkg.py'

I did not use those states when I tested the patch, so it looked okay.

We definitely don't want to merge this. I'm going to close this but we can discuss a path forward in #32500.

[mephi42]

No problem, let's discuss the possible alternatives there.
