Remove the cic-data-server related code and cleanup directory structure
The code in services/cic-data-server is not being used right now and can be removed.
move the cic-data-tasker directory to the top level and rename to cic-data. move the mod.go file under the new cic-data file
code under common/ should be moved under the new cic-data directory.
We will add an api webserver for cic-data to be implemented in a future issue. Two directories under cic-data/cmd can separate the main.go files for these applications. Two different binaries can be created: cic-data-tasker (for fetching cic data) and cic-data-server (for running an api webserver).
