Octavia: update/upgrade tasks to remove octavia_tls_proxy is no longer necessary

[Takashi Kajinami]

The octavia_tls_proxy was removed during the Rocky cycle by the following commit.

https://review.opendev.org/c/openstack/tripleo-heat-templates/+/636380

The above commit added update/upgrade tasks to remove the octavia_tlx_proxy container
but these tasks are still left even in the latest master.

Because we don't expect that container is created in recent releases, we should remove such unused tasks.

    Octavia: Remove unused cleanup tasks of tls_proxy container

    The octavia_tls_proxy container was removed during the Rocky cycle by
    commit f4460a580d24a709a4b2dede807b57fa9ab24f2b .

    The octavia_tls_proxy container might be deployed in an old Queens
    deployment but the container should be deleted when the deployment is
    updated/upgraded to one of
     - Latest Queens (before to Train)
     - Rocky
    so the cleanup step is no longer required in Stein and later.

    Closes-Bug: #1933712
