Test with older httpcomponents-client-5

#1103 describes the
issue.

Ubuntu 22.04 and Debian without Docker listening on port 2375 fails
tests when testing with apache-httpcomponents-client-5-api
5.4-118.v199115451c4d . The same tests pass if tested with
apache-httpcomponents-client-5-api 5.3.1-110.v77252fb_d4da_5

Ubuntu 22.04 and Debian with Docker listening on port 2375 passes
tests with both versions of apache-httpcomponents-client-5-api
