What is the problem this feature will solve?

• Slow certificate registration when using a managed service (like GCP certs)
• Save time with AWS, Azure environments with having a multi cloud certificate issuer
• Securing internal communications between apps (e.g. opensearch)

What is the feature you are proposing to solve the problem?

Add cert-manager integration: https://cert-manager.io/ to the OSDFIR charts.

This can be done within the ingress.yaml specification and adding the chart as a sub dependency to the other charts.
