Parameters common to all provisioners:

- `pause_before` (duration) - Sleep for duration before execution.

- `max_retries` (int) - Max times the provisioner will retry in case of failure. Defaults to zero (0). Zero means an error will not be retried.

- `only` (array of string) - Only run the provisioner for listed builder(s)
  by name.

- `override` (object) - Override the builder with different settings for a
  specific builder, eg :

  In JSON:
  ```json
  {
    "type": "shell",
    "script": "script.sh",
    "override": {
      "example_one": {
        "script": "basic_one-script.sh"
      }
    }
  }
  ```

  In HCL2:
  ```hcl
    build {
        sources = ["docker.example_one", "docker.example_two"]
        provisioner "shell" {
            script = "script.sh"
            override = {
                example_one = {
                    script = "basic-one-script.sh"
                }
            }
        }
    }
  ```

- `timeout` (duration) - If the provisioner takes more than for example
  `1h10m1s` or `10m` to finish, the provisioner will timeout and fail.
