- Increased number of supported topology nodes.
- To be improved with dynamic memory.

Context/Device/Service/PathComp/tests/WebUI component fixes and improvements

See merge request teraflow-h2020/controller!173

- renamed device type OPTICAL_LINE_SYSTEM to OPEN_LINE_SYSTEM

Common:
- renamed device type OPTICAL_LINE_SYSTEM to OPEN_LINE_SYSTEM
- added DATACENTER and EMULATED_DATACENTER device types.

Context:
- modified service constraints for test object to use nomenclature "metric[unit]"
- corrected ConstraintModel dump methods

Device:
- uncommented dump methods in database ContextModel and TopologyModel

OFC'22 / OECCPSC'22 tests:
- renamed device type OPTICAL_LINE_SYSTEM to OPEN_LINE_SYSTEM

WebUI:
OFC'22 / OECCPSC'22 tests:
- renamed device type OPTICAL_LINE_SYSTEM to OPEN_LINE_SYSTEM

- added object factory method for emulated datacenters

- Fixed instantiation parameters in Dockerfile

Common:
- Added missing object factory methods for constraints

Context:
- Adapted unitary tests to new constraint object factory methods

Service:
- Adapted unitary tests to new constraint object factory methods

PathComp-Backend:
- Deactivated health probes since it causes problems in backend REST server

PathComp-Frontend:
- Correct unitary test constraints for SP algorithm
- Adapted unitary tests to new constraint object factory methods
- Fixed instantiation of ShortestPath and KDisjointPath Algorithms
- Ignore unknown constraints in Algorithm request composition

Frontend:
- added show logs script
- improved config settings to get address and port of the backend
- improved logging of _Algorithm
- implemented KDisjointPath logic

Backend:
- added show logs script

- Fix CI/CD pipeline

- correct unitary test constraints for SP algorithm

- Fix CI/CD pipeline
- Correct log argument to make it screen-only
- Remove old data files
- Activate health probes

Adding friendly traces for debugging purposes in the process of parsing the context JSON

- Added support of the GET method to check status of PathComp
-Added support for showing logs via either Screen (stdout) or defined Log file

- Added deploy script used for tests

- Finished implementation of KDisjointPath algorithm
- Adjusted Algorithm interface
- Moved documentation and example test commands to misc folder

Common:
- temporarily added backend to pathcomp service for debug purposes

Proto:
- Added KDisjointPath Algorithm to pathcomp proto

Frontend:
- refactored Servicer to cope with multiple algorithms
- added implementation of ShortestPath algorithm
- added implementation of KShortestPath algorithm
- added implementation of KDisjointPath algorithm (partial)
- moved PathComp servicer tools to algorithms subfolder
- added new unitary test scenario (DC's with CellSiteGWs and Transport Network) to validate KDisjointPath algorithm

- integrated in deploy.sh script
- defined manifest
