[Observium] Restrict config access to users

Hey Adam (and all),

I asked about this previously but never heard back.

I'd really like a way to give people the ability to see a device but not see the config tab. We've got rancid integration turned on, and I want to give specific users access to see devices, but they shouldn't be able to see the device configs.

Hopefully it would be easy to do (maybe say users with a level of < X can't see that tab)

Thanks!
