Add the sanity check for docker image

[git-hulk]

We'd better add some sanity checks in:

kvrocks/.github/workflows/kvrocks.yaml

Lines 292 to 309 in 7f0c515

	check-docker:
	name: Check Docker image
	needs: [precondition, check-and-lint, check-typos]
	if: ${{ needs.precondition.outputs.docs_only != 'true' }}
	runs-on: ubuntu-20.04
	steps:
	- uses: actions/checkout@v3
	- name: Get core numbers
	run: echo "NPROC=$(nproc)" >> $GITHUB_ENV
	- uses: docker/build-push-action@v3
	with:
	context: .
	build-args: MORE_BUILD_ARGS=-j${{ env.NPROC }}
	push: false
	tags: kvrocks:ci
	outputs: type=docker
	- name: Test built image
	run: docker run --rm kvrocks:ci -v

As mentioned in the comments, we at least check if the docker listening port can be accessed from outside.

How about using the following commands? @git-hulk

id="$(docker run --rm -d -p 6666:6666 kvrocks:ci)"
sleep 1m # waiting for the periodic container health check

if [ "$(docker inspect --format='{{.State.Health.Status}}' $id)" != "healthy" ]; then
  echo "Container is not healthy."
  exit 1
fi

if [ "$(ss --listening --no-header --tcp '( sport = :6666 )')" == "" ]; then
  echo "The container listening port can not be accessed from outside."
  exit 1
fi

docker stop $id

@jyf111 Looks good, thank you.
