Ensuring that CSI drivers get deployed for testing exactly as intended
was problematic because the original .yaml files had to be converted
into code. e2e/manifest helped a bit, but not enough:
- could not load all entities
- didn't handle loading .yaml files with multiple entities
- actually creating and deleting entities still had to be done in tests
The new framework utility code handles all of that, including the
tricky cleanup operation that tests got wrong (AfterEach does not get
called after test failures!).
In addition, it is ensuring that each test gets its own instance of the
entities.
The PSP role binding for hostpath is now necessary because we switch
from creating a pod directly to creation via the StatefulSet
controller, which runs with less privileges.
Without this, the hostpath test runs into these errors in the
kubernetes-e2e-gce job:

The extra role binding is silently ignored on clusters which don't
have this particular role.
At present, endpoints and services are created
for glusterfs pvcs are in form of glusterfs-dynamic-<PVC name>
however this could cause issue if user deletes a PVC and immediately
creates a new one with the same name, PV controller will try to delete
the old PV and its endpoint and at the same the controller will try to create new PV
and the same endpoint. Depending on which event reaches the
controller first, it may create new PV, check that endpoints exists,
then delete the old PVC and delete endpoints already used by the new PV.
This patch changes the endpoint/service name to below format:
`glusterfs-dynamic-<PVC UUID>`.
By the uniqueness of UUID, above mentioned issue will no longer be present.

When we get an unsupported provider message, it often isn't clear what
method actually failed - add more information to the error message.
Issue #70280
The closing bracket in the link was automatically included in the link HREF.
Myself and @lurraca used standard markdown formatting to prevent that from happening.
Setting command line arguments via env variables that are not needed
by the binaries is just unnecessarily complex. The driver renaming
code in the E2E manifest PR would have to be made more complex to deal
with such a deployment. It is easier for that code and humans who look
at the .yaml file to remove the indirection.
