[V2] Add dockerfile and helm chart for each component

### Motivation: Why do you think this is important?

In order to deploy all flyte components separately, we need to:
1. Add/update the dockerfile in each flyte component(actions, cache_service, data_proxy, events, executor, runs)
2. Add a flyte-core dir under charts folder, and add the helm charts for running each component separately. We can refer to what we've done in [v1](https://github.com/flyteorg/flyte/tree/master/charts/flyte-core)

### Goal: What should the final outcome look like, ideally?

We can test in local k3s cluster and make sure each component was deployed successfully
