we basically want all RPMs to be built inside the container image build (strikethrough means we have that working): 

• opentracing-cpp
• jaegertracing-cpp-client
• openresty-pcre

• openresty-zlib

• openresty

• luarocks
• gateway-rockspecs-native
• gateway-rockspecs

for example, for opentracing-cpp:

the yum install opentracing-cpp-devel in https://pkgs.devel.redhat.com/cgit/containers/3scale-amp-apicast-gateway/tree/Dockerfile?h=3scale-amp-2 with a separate stage in our docker build that installs the necessary files, the same way this happens in https://pkgs.devel.redhat.com/cgit/rpms/opentracing-cpp/tree/opentracing-cpp.spec?h=3scale-2.13-rhel-8
