Replace usage of _pulp_client with pubtools-pulplib [RHELDST-141]

[negillett]

This commit removes the library's native _pulp_client ("legacy") and replaces it with usage of pubtools-pulplib methods for associating and unassociating content.

Additionally, PulpActions were replaced with simple abstractions for grouping content to be associated/unassociated.

Tests were removed/edited as necessary.

I'm at a total loss as to why we're seeing error 111 on '/api/v1/manifest'. I've touched nothing in the ubi client. Any ideas, @rbikar?

I think the ubi-manifest service in the test env was in a bad shape, I re-ran tests and they passed OK.

@rbikar, @rohanpm, this is ready for review. I'm still unsure why some modulemd profiles no longer contain "[d]" to signal default but I don't believe the change was introduced here (it was only ever present in the integration tests). It could be a difference between rhel7 and rhel8 content--this is a key difference between the two integration tests that asserted the presence of the mark.

In realistic usage the ubi7 shouldn't have any modules (but I guess in test the situation can be different).

Anyway you need to examine modulemd_defaults units in the test instance of rhsm-pulp before and after the test.

I checked current real ubi8 image and e.g. for perl module I get this: Output of dnf module list

and corresponding modulemd_defaults unit in production rhsm-pulp data: (Maybe the testing code reads wrongly the output as in terminal the formatting doesn't look very nice)

...
            "name": "perl",
            "profiles": {
                "5.24": [
                    "common"
                ],
                "5.26": [
                    "common"
                ],
                "5.30": [
                    "common"
                ],
                "5.32": [
                    "common"
                ]
            },
            "pulp_user_metadata": {},
            "repo_id": "ubi-8-for-x86_64-appstream-rpms__8",
            "stream": "5.26"
        },
...

which say 2 things:

• what profile is default for which stream
• what stream is default for the module

so it should be dependent on the data in pulp only, can you double-check the removal and copy of modulemd_defaults units? There might some subtle bug (or the formatting problem as I mentioned above).
