Pulsar: Lists all Functions deployed in a given namespace using API does not work

[bbonnin]

Describe the bug
Context: the function workers are not in the brokers.
When invoking the service URL of a function worker to get the list of deployed functions in a given namespace, the response is 404 Not Found (while there are functions deployed).

To Reproduce
Steps to reproduce the behavior:

1. Run a function worker
2. Deploy a function using the admin url of the function worker
3. Get the list of currently deployed functions in a namespace (pulsar-admin --admin-url http://my-host:6750 functions list --namespace my-namespace --tenant my-tenant)
4. The response is HTTP 404 Not Found

Also test with curl, same result.
If the worker run in a broker, the response is correct.
The other pulsar-admin commands such as functions create are working.

Expected behavior
A clear and concise description of what you expected to happen.
