Combine all RPC modules in one

Description

This MR aims at fixing issue #126 (closed) by combining all the RPC modules into one as it creates confusion with the templated RPC framework. Currently, in the cmsgemos code, we have 8 RPC modules:

• amc
• calibration_routines
• daq_monitor
• expert_tools
• gbt
• optohybrid
• utils
• vfat3

These are combined into one, named gem_rpc using the module_init function while keeping the separation in the correct namespaces and files. The new file has been created and all the 8 modules and have called and the changes have been made in the build file.
