Alizer does not detect port if Dockerfile is not in the root directory

➜  python-debu ls -a
.          ..         .gitignore README.md  docker     go.mod     kubernetes main.go
➜  python-debu less docker/Dockerfile
➜  python-debu odo analyze -o json
[
	{
		"devfile": "go",
		"devfileRegistry": "DefaultDevfileRegistry",
		"devfileVersion": "1.0.2",
		"name": "python-debu"
	}
]
➜  python-debu cp docker/Dockerfile .
➜  python-debu ls
Dockerfile README.md  docker     go.mod     kubernetes main.go
➜  python-debu odo analyze -o json
[
	{
		"devfile": "go",
		"devfileRegistry": "DefaultDevfileRegistry",
		"ports": [
			8081
		],
		"devfileVersion": "1.0.2",
		"name": "python-debu"
	}
]

I am taking example of Go here, but this might be relevant for other projects as well.

Update: I've created a PR. It checks both for root and for second-level directories it may find inside the given root path.
