docs: Replace Helm "install" using "deploy" plugin

With Casablanca release "deploy" Helm plugin has become preferred way of
ONAP installation (even though it is a temporary solution).

This patch replaces all but one occurences of "helm install" command -
the remaining one is the placeholder for installation from osn repo.

It also imports plugin installation step from Quick Start Guide.
