request help: use name instead of id in grafana dashboard

[starsz]

Issue description

Hi, I found that now we use the service id and route id in the grafana dashboard.
Which is not friendly to read. So I recommend we can use name instead of id in the grafana dashboard.

Now:

Environment

• apisix version (cmd: apisix version): 2.6
• OS (cmd: uname -a):
• OpenResty / Nginx version (cmd: nginx -V or openresty -V):
• etcd version, if have (cmd: run curl http://127.0.0.1:9090/v1/server_info to get the info from server-info API):
• apisix-dashboard version, if have:
• the plugin runner version, if the issue is about a plugin runner (cmd: depended on the kind of runner):
• luarocks version, if the issue is about installation (cmd: luarocks --version):

The default label of Prometheus is id but not name. So by default, the grafana doesn't know the name.

[starsz]

Yes.I think we can use the name as the label of Prometheus if the name exists?

[spacewander]

No. It will be a break change. We can't change it in 2.x at least.

[starsz]

No. It will be a break change. We can't change it in 2.x at least.

In another way, we can add a config to switch the label.

[spacewander]

Do you mean a config for grafana? We have such a config for prometheus.

[starsz]

Oh. I see. We had already supported it.
