Add instrumentation for hotelReservation microservice
This microservice is written in go. To add instrumentation, the use of https://gitlab.mpi-sws.org/cld/tracing/tracingplane-go and https://gitlab.mpi-sws.org/cld/tracing/tracing-framework-go is required. I am not sure how to configure the project with both of those libraries but I imagine https://gitlab.mpi-sws.org/cld/systems/sock-shop would help in this.
