Service RecomputeConnections RPC method, Device Controller node pointer and Exclude Constraint

Protos:

• Context.proto: Added Controller field to Device entity
• Context.proto: Added ServiceStatus UPDATING
• Context.proto: Added Constraint Exclusions
• Service.proto: Added RecomputeConnections RPC method

Common requirements:

• Fixed grpclib package version

Common - Type Checkers - Assertions:

• Added ServiceStatus UPDATING
• Added ServiceStatus SLA_VIOLATED

Context component:

• Added ServiceStatus UPDATING and SLA_VIOLATED
• Added Constraint Exclusions
• Added Controller field to Device entity

Device component:

• Auto-enable devices when Automation component is not deployed
• Updated get/set device controller node

PathComp component - FrontEnd:

• Corrected deepness level of MicroWave devices/controllers
• Updated get device controller node
• Updated K-ShortestPath algorithm with k-inspection and k-return variables.
• Corrected get_reply logic in _Algorithm to support retrieval of multiple connections when KSP algorithm is requested

Policy component:

• Added ServiceStatus UPDATING
• Added ServiceStatus SLA_VIOLATED

Service component:

• Added RecomputeConnections RPC method to client
• Implemented RecomputeConnections RPC method in servicer
• Updated get device controller node in TaskExecutor
• Corrected issue formatting error message in TaskExecutor
• Added method compose_service_connection_update in TaskExecutor
• Implemented test case for RecomputeConnections RPC method

WebUI component:

• Added Controller field to Device details page
