Add 3.2.2 UBI / Clouseau reference container

Why:

Provide an example container that includes the current CouchDB
and Clouseau releases.

How:

- Clone the 3.2.0-ubi-clouseau directory to `3.2.2-ubi-clouseau`
- In `3.2.2-ubi-clouseau`:
  - Update CouchDB to 3.2.2
  - Update Clouseau to 2.21.0
  - Import and configure the SLF4J Simple logger. Clouseau 2.20.0
    removed Log4J in favour of SLF4J. For most container applications,
    logging to Console only should suffice. If alternative SLF4J
    backends are required they can be imported / configured
    in a similar fashion.
  - Add support for the `COUCHDB_ERLANG_COOKIE` environment variable
    in the Dockerfile entrypoint. This is not precisely the same as in
    the images without Clouseau because the `-ubi-clouseau` images
    already supported passing in a cookie via `ERL_FLAGS` and extracting
    it to configure `clouseau` (which needs the cookie to connect
    to CouchDB). In this Dockerfile, we always pass the cookie via
    `ERL_FLAGS` and will extract it from `COUCHDB_ERLANG_COOKIE` if
    passed.

Testing:

I verified that the container starts, I can create / query search
indexes etc. I tested passing in `COUCHDB_ERLANG_COOKIE` but have
not tested permutations beyond that.
