Currently istio-remote (for VPN connectivity and Split Horizon EDS) is a separated Helm chart/release.
We can achieve the same goal with having another values within the Istio chart tailored for the remote clusters installations.

What we gain:

• Better user experience
• Simpler and less confusing docs
• Easier to maintain and avoids (templates) duplications
• Get rid of the need to create the charts packages (helm dep update) by moving the subcharts back to the Istio release

We can remove the istio-remote chart and move subcharts back to istio or we can keep the istio-remote and mark it deprecated. Current PR removes it.
