Helm chart for pattern 2 does not allow to run without analytics

[rksk]

There are some situations where we need to run the cluster without analytics. But with the current design, every other pod is waiting for analytics to be ready even we make analytics replica count zero.

We could check the analytics replica count and avoid waiting for analytics if it is zero.

@rksk support for switching off Analytics support can be added to the <HELM_HOME>/values.yaml if necessary.

But @pubudu538 is this a valid use case as WSO2 API Management deployment patterns suggest default support for Analytics and no option to switch them off?

This is a valid use case. There can be cases where we run without analytics. So let's bring this feature to Helm.
