    Fix CI issues and adjust test jobs

    It is incorrect to install tempest and manila-tempest-plugin
    globally in devstack jobs. So this commit removes the use
    of the test plugin's devstack installation hook, and uses
    a "tempest-venv" that devstack sets up to run the tests.

    To allow zuulv3 style jobs elsewhere [1] use the right
    api versions when testing against this stable branch,
    we enhance the devstack plugin.sh script to set api
    versions as tempest configuration options.

    Alongside these changes, we can perform a much needed
    test job cleanup by eliminating some jobs we don't have
    the bandwidth to maintain:

    - manila-tempest-dsvm-postgres-generic-singlebackend
      Single backend jobs are not very useful - the job
      sets up a single backend in a multibackend style.
      We've dropped this from future branches, and we
      don't expect this job to catch any regressions that
      other jobs will miss.
    - manila-tempest-dsvm-generic-no-share-servers
      This job's been failing; and wasting CI resources.
      We have other DHSS=False reference drivers (CephFS
      native/nfs, ZFSOnLinux, LVM) where we test the
      driver mode sufficiently.
    - manila-tempest-dsvm-glusterfs-nfs-heketi
      and manila-tempest-dsvm-glusterfs-native-heketi
      these were in the experimental queue, unmaintained
    - manila-tempest-dsvm-container-scenario-custom-image
      and manila-tempest-dsvm-generic-scenario-custom-image
      New zuulv3 style jobs in the manila-image-elements
      project replace these jobs [2].
