Podman: APIv2: libpod endpoint not working

[liquidat]

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

I tried to get the APIv2 working. The docker endpoint works, but the libpod endpoint does not.

Steps to reproduce the issue:

1. In one terminal: podman system service --timeout 5000

2. In a second terminal: curl -s --unix-socket /$XDG_RUNTIME_DIR/podman/podman.sock http://localhost/images/json

3. Afterwards, in the second terminal: curl -s --unix-socket /$XDG_RUNTIME_DIR/podman/podman.sock http://localhost/libpod/images/json

Describe the results you received:

The docker endpoint works as expected:

$ curl -s --unix-socket /$XDG_RUNTIME_DIR/podman/podman.sock http://localhost/images/json
[{"Id":"8c2e0da7c436e45be5ebf2adf26b41d13939190bd186214a4d45c30485071f9f","RepoTags":["registry.fedoraproject.org/fedora:latest"],"Created":1583300892,....

However, the libpod endpoint does not work:

$ curl -s --unix-socket /$XDG_RUNTIME_DIR/podman/podman.sock http://localhost/libpod/images/json
Not Found

However, ping works for both:

$ curl -s --unix-socket /$XDG_RUNTIME_DIR/podman/podman.sock http://localhost/_ping
OK
$ curl -s --unix-socket /$XDG_RUNTIME_DIR/podman/podman.sock http://localhost/libpod/_ping
OK

Describe the results you expected:

The libpod endpoint should show the images as well.

the libpod endpoints are all versioned ...

i.e. http://localhost/v1.24/libpod/images/json

Awesome, thanks for the answer, sorry for the noise.
