Support server name signature for private plugins

[FStefanni]

Hi.

What would you like to be added:

It would be nice to be able to sign a private plugin once, for a group of grafana instances, related to some server(s) names.
At the moment it is required to add an explicit --rootUrls for each installation, which is not suitable in case of many grafana installations. So the suggestion is:

• To allow a mismatch of root_url configuration and signature, as long as the signature is the domain. For example, signing for www.myserver.com should allow enabling the plugin in www.myserver.com/grafana1 and www.myserver.com/other/grafana2
• To allow wildcard sub domains, *.myserver.com: to enable the plugin for each instance of grafana running on any matching sub-domain (e.g. grafana.myserver.com and support.me.myserver.com)

It should suffice to allow to pass --rootUrls www.myserver.com or --rootUrls *.myserver.com to enable the suggested signatures.

Why is this needed:

It is required in case of many grafana instances. In my case, we have in production more than 40 grafana instances, on 3 different servers. At the moment, we should sign our private plugin for each single grafana instance, which is not feasible. moreover, we should re-sign it for any new installation (again, it is a huge overhead).

Regards.

Hi @FStefanni - thanks for the contribution.

It's a great idea - one we have actually been speaking about recently and are planning to address it soon, starting with a design doc. The examples you provided I would think cover a high percentage of use cases, so that might likely be the first step, but still TBD.

Hi,

great :) I'll wait for this feature in the next releases then.

Hi!

Really like this idea (well, actually we need this). We build our Grafana instance with custom (in-house) plugins once and deploy it to different sites, all running in different subdomains: grafana.test1.example.com, grafana.test2.example.com, grafana.test3.example.com etc.

The amount of sites is unknown when building the image (and thus when signing the plugin) so some sort of wildcard support would help us out in this scenario.
