Update deprecated elasticsearch components

[edaena]

Elasticsearch is deprecating the charts in the helm repository in favor of the official Elastic Helm Chart.

• Upgrade existing elasticsearch component

As mentioned in #10543 we are planning on deprecating this chart in favour of the official Elastic Helm Chart. We have made steps towards that goal by producing a migration guide to help people switch the management of their clusters over to the new Charts. The Elastic Helm Chart supports version 7 of Elasticsearch and it was decided it would be easier for people to upgrade after migrating to the Elastic Helm Chart because it's upgrade process works better. During deprecation process we want to make sure that Chart will do what people are using this chart to do. Please look at the Elastic Helm Charts and if you see anything missing from please open an issue to let us know what you need. The Elastic Chart repo is also in Helm Hub.
