Consider moving `irods.test.helpers.make_session` into `irods.helpers`

[alanking]

It seems that this irods.test.helpers.make_session function has grown to be useful beyond just the tests. Should we move it into this module so that it can be used directly? If so, let's create an issue to look into that some other time (i.e. don't do it as part of this change). The existing version in irods.test.helpers can then call the new one with its existing default value(s) to minimize the blast radius.

It may or may not be beneficial to do this, but I didn't want to lose the idea, so here's the issue. :)

FYI: I remember this https://github.com/irods/python-irodsclient/issues/412 because waiting for an enhancement to use make_session easily where needed.

@mstfdkmn - Good catch. Perhaps this can be closed as a duplicate of #412. Thoughts, @d-w-moore?

[d-w-moore]

Yes, this PR probably sets us on a particular path for addressing #412. As to what's the better name, irods.utility, irods.misc or irods.helpers, I don't know. I usually defer to the consensus. Have there been any other PR's around that attempt to establish a common space for utility functions and such?

There's already an irods.session module. Why not put it in there?

from irods.session import make_session

[d-w-moore]

@korydraughn I'm ok with that. So then we keep #412 around for now, and consider whether it may or may not be addressed by the creation of irods.helpers.xml_mode and the namespace / package in which it resides?

[korydraughn]

Sounds good to me.
