Define Services basic configuration in configuration file

It would be good to have the basic configuration for the service defined in a configuration file and not hardcoded into main.cc.

A potential solution to this would be to have a config.cc and config.h that have a config structure that holds all the info regarding system configuration details such as;

• serverPort
• logFile
• logLevel

Perhaps this will be small initially but can be made bigger down the line.

From the command line the service's executable would therefore only require a configuration file holding the config settings for the system.

Potential tools:

• CLI11 for command line and config file parsing
