Configuring APIcast with OpenTracing in 3scale fails

Issue

We are trying to enable support for OpenTracing as described in https://access.redhat.com/documentation/en-us/red_hat_3scale_api_management/2.9/html/administering_the_api_gateway/operating-apicast#configuring_apicast_with_opentracing

If we start APIcast with the environment variable OPENTRACING_TRACER set to Jaeger, we get the following error during startup:

ERROR: /usr/local/share/lua/5.1/liquid.lua:2437: error when getting template "conf.d/opentracing/Jaeger.conf.liquid": /opt/app-root/src/conf.d/opentracing/Jaeger.conf.liquid: No such file or directory

A quick look into the APIcast container revealed that the file in the container is all lowercase: /opt/app-root/src/conf.d/opentracing/jaeger.conf.liquid

As far as the documentation tells, we don't need to configure anything related to that jaeger.conf.liquid file.

Please provide assistance in resolving this issue. Thank you!
