- Implemented support for ACLs
- Added suport for Candidate datastore

- Added Routing Policies as special resource for interrogation during initialization
- Added flags in unitary tests to control which tests to be executed in OpenConfig.
- Added run-test-locally specific for device component.

OpenConfig Driver:
- Implemented routing policy templates, parsing and configuration.
- Implemented retry decorator for NetConf client.

Scripts:
- added missing commands to script run_tests_locally.sh

Device:
- added key formatting inside unsibscribe from monitoring
- added termination attribute in GetState to properly interrupt monitoring loops

Service:
- arranged service component testing, missing fixtures

Monitoring:
- added missing environment variable INFLUX_PORT

Device:
- Implemented Driver API with some special resources to enable retrieving endpoints from devices, interfaces, and network instances.
- Implemented special resource_keys (_connect/*) to enable AddDevice to obtain settings used to connect to remote devices (address, port, username, password, etc.)
- Implemented Emulated Driver (only for testing)
- Implemented OpenConfig Driver (missing to implement monitoring; templates for Infinera devices to be tested with other device vendors)
- Minor bugs and code improvements
- Improved test unit to enable easy testing of vendor devices and keep credentials secret.

- reorganized some files and modules
- implemented discovery of device endpoints for OpenConfig driver
- implemented retrieval of current configuration for OpenConfig driver
- updated test units and separated in emulated and openconfig test sets

- added missing proto files in genproto.sh
- created .gitignore files to prevent sharing device credentials and data
- improved MonitoringLoops class with one thread per driver for data collection, a unique aggregation queue and one single thread for data export to monitoring
- added GetResource method to Driver API
- improved DriverFactory to select the driver that better fits with filter fields in terms of number of correspondences in filter fields. Drivers with some mismatch filter are discarded.
- implemented proper initialization and connection of drivers to real devices
- started to implement OpenConfig driver with support for Infinera Packet Routers

- Finished preliminary implementation of Emulated Driver
- Emulated Driver uses APScheduler to emulate subscriptions
- Implemented basic unitary testing for Device Driver API
- Still pending to integrate Driver API within Device service

- Implemented GetConfig/SetConfig/DeleteConfig
- Implemented unit tests for GetConfig/SetConfig/DeleteConfig
- Implementing simple DiscriteEventSimulator to emulate monitoring
- Remains to implement SubscribeState/UnsubscribeState/GetState
- Remains to implement unit tests for SubscribeState/UnsubscribeState/GetState
