network trust level in grafana

[guaka]

Idea came up thinking about how to do trust on nostr, https://github.com/Trustroots/nostroots/issues/20

It would be great to have this trust information in grafana:

• Met in person
• I hosted them
• They hosted me
• Apart from your personal experience, would you recommend others to meet them?

Both positive and negative.
