[521] Add support for new API for adding groups for versions >= 4.3.4

[JustinKyleJames]

I tested adding groups via metalnx in 4.3.3, 4.3.4, and 4.3.5. The jargon-core tests also passed.

Change look good.

Please add a test for this. We need to make sure the new test passes against 4.3.3 and 5.0.1.

Looks good. Squash it.

There is already a test that covers this. It is UserGroupAOImplTest.testAddUserGroup. It covers this.

As for testing against 4.3.3 and 5.0.1, that was tested via point Metalnx to iRODS servers at these versions (as well as 4.3.4).

We don't have a testing environment setup to run the unit test listed above in 4.3.3 and 5.0.1 at the moment though I did open an issue to create a 5-0 testing environment setup.
