    Eulation for XrDriver endpoints

- Arranged .gitignore & .gitkeep files in common proto folder
- Created specific run_tests_locally script for Context component
- Moved imports from *.proto folder to common.proto folder
- Adapted common.tools.object_factory to new proto definitions for ConfigRule and Constraint
- Extended common.tools.type_checkers to new proto definitions for ConfigRule and Constraint
- Removed context's genproto.sh script
- Adapted Events generated to new timestamp data type
- Minor code and linting fixing

- not functiona, just skeleton to generate the demo paper.
- logic for disjoint paths to be implemented

- defined unified constants for all micro-services
- defined common settings getter methods
- defined generic gRPC servicer
- defined generic Rest servicer
- defined common MockServicer for Monitoring component
- removed old common/tests MockService class; to be replaced by new generic gRPC servicer
- minor code formatting/styling

- code styling and cleanup

new development of microwave device - implemented the Api to get configurations, create and delete services
