Fix the heat-container-agent docker image

There are 2 fixes included in this patch:

1. A regression issue introduced by the multi region patch,
   see https://review.openstack.org/#/c/579043 for more details.
   There is a missing bracket.
2. Issues in the Dockerfile of heat-container-agent. Some depedencies
   are renamed or we don't really need them. And because of the
   multi region bug, we need a new version for os-collect-config. So
   switching to pip from dnf is much eaiser than building a new RPM
   package for those python libs we care about. To be more clear,
   for the multi region issue, we need os-collect-config 9.1.0, and
   with dnf you can only find 5.0.0.
