As part of DCAE transformation, require all remaining DCAE services involved to be migrated for deployment support via helm.

Expectation:

1. Deliver Son-handler component as separate helm chart employing dcaegen2-service-common template under https://git.onap.org/oom/tree/kubernetes/dcaegen2-services/components 
2. Continue blueprint revision required for Istanbul release for backward compatibility for CLAMP/Policy usecases
3. Update MS documenation to reflect new deployment steps using Helm 
4. Update Integration/robot test-suite to use helm deployed MS 
5. Components with policy configuration depedendency (SON-Handler, TCAGEn2/policy) should switch to retrieve policy configuration using sidecar container (https://wiki.onap.org/display/DW/Policy+function+as+Sidecar)   - tracked as separate task under DCAEGEN2-2711

Note: There is ongoing work with OOM team to move the charts to DCAE repository; once this is complete - new contribution will be under DCAE Repo

All container updates and charts updates are required to be completed by M3 (Final code submission)
