fork of the Istio helm templates, refactored to increase modularity and isolation.

Goals:
- Improve upgrade experience: users should be able to gradually roll upgrades, with proper
canary deployments for Istio components. It should be possible to deploy a new version while keeping the
stable version in place and gradually migrate apps to the new version.

# The original version of this file is located at /manifests/helm-profiles directory.
# If you want to make a change in this file, edit the original one and run "make gen".

# The stable profile deploys admission control to ensure that only stable resources and fields are used
# THIS IS CURRENTLY EXPERIMENTAL AND SUBJECT TO CHANGE
