OISP-Agent Migration to IFF

[wagmarcel]

oisp agent needs to migrated to IFF

• OISP-aid will become the Keycloak tenant name
• Remove all rest calls to OISP
• Onboarding is done with the new IFF onboarding method (we will create a standalone script for that in IFF-DT project)
• Birth message needs to be dynamic because agent does not know the metrics names from the beginning

• Keycloak : onbaording token and device token information on the link
  https://github.com/IndustryFusion/DigitalTwin/issues/400

• What will be DATATYPE of the data message? String-> check if integer or char at server

• No device registration now.

• The device will get an onboarding token from the user as environment variable

• No use of oisp-admin probably.

• Onbaording using scripts done
• IoT agent, admin stripped down , stripping agent part still in progress

• Agent code for device Birth and data submission adopted as per new flow
• Fixing issue received while running ngsild-agent in progress
