[ovn_central] call podman exec without a timeout

This is a workaround fix of a podman bug (see rhbz1732525) where "podman ps" can hang when "podman exec .." is invoked in detached mode under "timeout". Calling it without timeout works fine. This commit can be reverted once the podman bug is fixed. Resolves: #1875 Signed-off-by: Pavel Moravec <[email protected]>
