config changes

• Instead of having separate variables, I added a struct which holds configuration parameters
• Deleted PEMReader.go file
• Added CheckConfigValues and CalculateConfigValues functions
• Defined required, optional and calculated config values
• Changed Makefile so that on local environments, the git branch will be used as version
• Changed run.sh so that on local environments, config.yaml will be used for configuration file
