IPv4/IPv6 dual stack support in ONAP (Istanbul)

Description of Use Case / Requirement:

Majority of LTE and 5G RAN networks today are running exclusively on IPv6. IPv4/IPv6 dual stack solution for ONAP is needed to enable integration. Continuation of REQ-385 and REQ-432

In Istanbul release the scope is so far:

• An update of OOM Helm charts, using the K8S 1.20/1.21 IPv4/IPv6 DS model ("PreferDualStack"):
  • At least for DCAEGEN2-Services
  • Preferably in "common OOM Helm chart template".
• An update of OOM Helm charts for EJBCA server to version 7.x.
  • EJBCA 7.x supports requesting certificates using IPv6 addresses.
  • This task can be executed only after EJBCA 7.x is available as a Docker container.
