Description of problem:
=======================
The issue w.r.t. Grafana panel is fixed (check https://bugzilla.redhat.com/show_bug.cgi?id=2133762), but still warning msgs regarding "vonage-status-panel" are observed in the podman logs


Version-Release number of selected component (if applicable):
==============================================================
16.2.10-160.el8cp


How reproducible:
=================
Always


Steps to Reproduce:
===================
1) Deploy a ceph cluster with dashboard enabled (build - 16.2.10-160.el8cp).
2) Use command #ceph dashboard get-grafana-api-url to get the Grafana API url
3) Through CLI, run the command on node where Grafana service is running - # podman logs $(podman ps | awk ' /grafana/ { print $1 } ') | grep -i skipping


Actual results:
===============
[root@ceph-saraut-5-3-z2-y4i1cu-node1-installer ~]# podman logs $(podman ps | awk ' /grafana/ { print $1 } ') | grep -i skipping
t=2023-04-04T08:37:26+0000 lvl=warn msg="Skipping finding plugins as directory does not exist" logger=plugin.finder dir=/usr/share/grafana/plugins-bundled
t=2023-04-04T08:37:26+0000 lvl=warn msg="Skipping loading plugin due to problem with signature" logger=plugin.loader pluginID=vonage-status-panel status=unsigned


Expected results:
=================
As mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=2133762#c30; the warning messages because we are installing the plugin, we should NOT be seeing the warning messages.
