InitContainer can not get packages from Istio Enabled cluster #502
Description
Affecting Version: Function Mesh 0.7.0
#411 introduced an initContainer to download the package for the function runner, but with no luck on Istio enabled cluster.
Get "http://new-cluster-broker.default.svc.cluster.local:8080/admin/v3/packages/function/public/default/py-statful/latest": read tcp *.*.*.*:44734->*.*.*.*:8080: read: connection reset by peer
Istio provided some workaround on https://istio.io/latest/docs/setup/additional-setup/cni/#compatibility-with-application-init-containers, but it is not working if the mTLS is in STRICT mode on the cluster.
It is suggested to disable the init container feature on Istio enabled cluster, or make a feature flag to let the user do the config.
