Create Helm Chart from Static Manifests
**What type of PR is this?** /kind feature **What this PR does / why we need it**: This PR convert our static deployment manifests from `deploy/kubernetes/*` into Helm Charts under `charts/*`, by running a convert script under `deploy/util/chart-releaser.sh`. Moreover, it handle the chart release with branch `gh-pages`, by integrate with https://github.com/helm/chart-releaser-action. The sample helm repo could find from https://alvistack.github.io/kubernetes-csi-external-snapshotter/index.yaml, by: helm repo add external-snapshotter https://alvistack.github.io/kubernetes-csi-external-snapshotter helm repo update helm search repo external-snapshotter Before each stable tag release, maintainers only required to: 1. Run the `./deploy/util/chart-releaser.sh` and update templates under `charts/*/templates/*` 2. Double confirm `charts/*/values.yml` with correct values, e.g. image tags 3. `git add --all --force charts/* && git commit` Signed-off-by: Wong Hoi Sing Edison <hswong3i@pantarei-design.com>
