Device:
- Removed obsoleted run_tests_locally-device.sh script
- Moved imports from *.proto folder to common.proto folder
- Removed device's genproto.sh script
- Minor code and linting fixing
- Arranged requirements to accelerate Docker image creation

Monitoring:
- Moved imports from *.proto folder to common.proto folder
- Removed monitoring's genproto.sh script

- Migrated to use new generic gRPC servicer
- Migrated to use new generic Rest servicer
- Migrated to use new settings framework
- Migrated tests to use new generic servicers and mock's
- Solved bug with endpoint monitors' population (dupplicated sample types due to wrong key generation)
- Use Emulated driver when both driver and device type are not specified
- Separated unitary tests and execution scripts per device driver
- Extracted common unitary test functionalities into separate code files
- Minor code styling/formatting

- Implemented MonitorDeviceKPI RPC method
- Implemented Endpoint pre-configruation for Emulated Driver
- Implemented MockMonitoringService for testing Device monitoring capabilities
- Implemented Monitoring Loops to collect samples from drivers and forward them to Monitoring Service
- Test unit for Emulated Device Monitoring half implemented.
- Minor bug resolutions in OpenConfig Driver

Deactivated some Device monitoring functionality partially implemented to enable a functional commit into develop.

- Implemented Database models for KpiModel and KpiSampleType
- Added MonitorDeviceKpi to DeviceClient
- Added MonitorDeviceKpi to DeviceServiceServicerImpl (partial implementation)
- Created MonitoringLoops class (partial implementation)

Common:
- Normalized report_coverage_*.sh scripts, and temporarily summarized results in device one for testing purposes.
- Adapted run_tests_locally.sh script for testing purposes
- Improved message synthesis of ServiceException

Context:
- Improved ConfigModel helper functions

Device (intermediate backup):
- Removed DataCache since it reduces readability of the code. Moved database one level up.
- Improved ServicerImpl and moved DataCache functionality over there.
- Added condition to prevent AddDevice request from carrying a configuration.
- Multiple pre-work required for processing configuration differences in DeviceServiceServicerImpl.

Preliminary unfinished version of device service and Context API based on Redis. To be finished, it is just a backup.

This reverts merge request !3

Move database to common folder, since it will be used also by device service, and implement very minor changes.
