Dapr CLI Docker Container

## Describe the proposal

Dapr should provide a container which contains the dapr cli preinstalled on it. A usecase may be when you want to run a kuberentes job using Dapr CLI:

```
apiVersion: batch/v1
kind: Job
metadata:
name: dapr-cli
spec:
template:
spec:
containers:
- name: dapr-cli
image: daprio/cli
command: ["dapr", "..."]
```

As discussed in https://github.com/dapr/cli/pull/1339 this Issue is for determining if there is enough interest in Dapr creating and supporting a Github action pipeline and docker container.

## Release Note

RELEASE NOTE: **FEATURE** Creates new Workflow to publish Dapr CLI to Docker Hub
