This commit provides support for automated invokation
of the ztpUpdate RPC upon a DEVICE_UPDATED event.
When this event is triggered, the Automation component
fetches the associated device configuration and applies
it to the device.

Common:
- Extended context proto with 2 methods: UnsetService and UnsetSlice

Context component:
- Added timestamp to logs
- Added methods UnsetService and UnsetSlice to Context client
- Implemented methods UnsetService and UnsetSlice in Context servicer
- Resolved conflict between service and slice entities with constraints and configrules

    Initial code for XR Device Driver, can connect to CM and acquire access token. No other functionality

- Slice: added config rules
- Added EndpointPriority constraint
- Modified IsolationLevel constraint to contain a repetition of items

ACL:
- defined generic model for ACLs

Context:
- Extended context.proto with ConnectionSettings
- Extended context.proto with ConfigRules specific for ACLs
Extended context.proto with Constraints for Schedule, Location, and SLAs
- created ContextPolicy to bring persistent storage of policies
- updated genproto.sh

Policy:
- added missing message to list PolicyRuleIds

- formatted and corrected interdomain and slice proto files
- regenerated associated Python code files per component

Updated gRPC proto files to prevent trouble with KPI sample types in devices, also updated files related to this issue.

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.
