Minor bug fixes.

Package upgrades, etc

deployment/noheat refactorization, fixes and updates:

• updated Ansible, Galaxy collections and Python libs to latest versions
• better Galaxy collections and Python libraries versions management
• added playbook to deploy Devstack
• added option to deploy Istio
• ability to set arbitrary overrides file
• added one playbook to deploy whole infrastructure (i.e. create OpenStack VMs in which Devstack, k8s and ONAP gets deployed)
• documentation updates

SO improved flows around the CNF orchestration, CNF Upgrade, minor bug fixes around the slicing usecase.

It also includes Security and minor functional bug fixes.

Key updates for 5G SON use case include:

• Modification of RAN control loop flows so that we have specific control loop flows for O1-based and A1-based RAN actions. This includes changes in Policy, SDN-R, SON-Handler MS, and RAN-Sim.
• Enhancement of RAN-Sim to support A1-based action with new modules for (a) A1 Termination, (b) ran-app to provide xApp/Near-RT RIC abstraction. The A1 Termination is harmonized with OSC work, and the ran-app has an interface to the RAN-Sim controller and simulated RAN NFs.
• Modification of Control Loop message formats and policies to direct O1 and A1 flows appropriately

E2E Network Slicing

The key updates for E2E network slicing in Kohn release include:

• Slice Analysis MS enhancement to support real-time intent listening using DCAE SDK dmaap-client lib
• KPI Computation MS enhancement to support new KPI reporting to UUI, KPIs spanning multiple resources and error handling for missing counter
• Contribution to DCAE R11 Global requirements 

Enhanced and robust KPI computation. Support for IBN based slicing in future releases.
