Change ADO logic to use helm-charts-azure

Requirements (Updated)

We started initial migration for osdu-base/ osdu-istio helm chart to helm-charts-azure, this was affecting customers, we decided to rollback.

• Need to rollback changes to use flux again for common and chart-* pipelines.

Requirements (Deprecated)

• Refactor current azure devops pipeline to get the helm charts for each service from the helm-charts-azure repo, instead of the devops/azure directory.
• Pipeline should create helm-chart in ACR as well to use that same helm-chart and common helm values to install new service instead of using flux.
• Add test for helm charts, lint, template in the pipelines steps.
• Allow option to choose osdu-azure subgroup install or single service install only.

User Documentation

• Refactor if needed documentation about services deployment.
