Add a new flag `--plain-http` to the following commands: * `helm install` * `helm pull` * `helm push` * `helm template` * `helm upgrade` * `helm show` This flag instructs the registry client to use plain HTTP connections, thus enabling upload/download of charts from OCI registries served at an HTTP endpoint.
