Fix multiple issues

Multiple issues combined to pass CI

1. drop tripleo-common-tempest-plugin

This is not needed plugin without any branches or releases. And wants Python 3
while we have Py2 for CentOS 7.

14:41 < hrw> is  tripleo-common-tempest-plugin your stuff?
14:43 <@EmilienM> yes and it does nothing. I thought we removed that?
14:43 <@EmilienM> apparently it's still here https://github.com/openstack/tripleo-common-tempest-plugin
14:43 <@EmilienM> we should burn it, weshay|ruck ^
14:44 < hrw> EmilienM: also fine to drop from train?
14:44 <@EmilienM> burn it everywhere you can
14:44 < hrw> THANKS
14:44 <@EmilienM> it has never been useful
14:44 <@EmilienM> and people who started it left
14:48 <@weshay|ruck> EmilienM, yup

2. Sensu: Remove ceph and process-checks plugins from client

The sensu image became unbuildable, failing to install the ceph plugin:

    Unable to resolve dependencies: sensu-plugins-ceph requires english (= 0.6.3)

This has happened because the author of the 'english' gem has seen fit
to publish a new 0.7.0 release, and 'yank' [1] all previous releases
from rubygems.

This change removes the ceph and process-checks plugins, which both
suffer from a dependency on the yanked english 0.6.3.

[1] https://rubygems.org/gems/english/versions/0.6.3

Closes-Bug: #1871600

(cherry picked from commit 2d1017be3f)

3. Use freezer queens releases

There are no freezer releases in Rocky, so these packages stayed on
master. This is now python 3 only, so fails to build. Pin to Queens
6.0.0 releases.

4. Pin elasticsearch gem to <7.6.0 in fluentd

Since the release of the elasticsearch 7.6.0 gem, the fluentd image
fails to build on Ubuntu due to a transitive dependency on faraday.

ERROR:  Error installing fluent-plugin-elasticsearch:
    faraday requires Ruby version >= 2.3.

Pin elasticsearch to <7.6.0.
