🌱 Add a way to run ETCDRestore controller locally

[furkatgofurov7]

What this PR does / why we need it:
This patch provides an alternative way to run Rancher Turtles locally using the turtles-dev script and Tilt. A new USE_TILT_DEV env var was introduced (set to true by default to keep previous behaviour), and a new way of deploying Turtles uses the locally built helm chart only when set to false.
Additionally, image building for new turtles-etcd-snapshot-restore was taken care by Tilt when used, however it is not when there is no Tilt. To run it without tilt, new Dockerfile to build the image for etcdrestore controller and use the built image in local testing.

Lastly, it changes nightly image publish GH action to publish etcdrestore image as part of the GHA.

Fixes: #765

Special notes for your reviewer:
When running uninstall locally with these changes, snapshot restore controller was cleaned up together with RT controller without any issues
