Dashboard reboot function

[erazor666]

Describe the problem you have/What new integration you would like
Sometimes I want to restart a node, and it may be in a difficult place to reach. A reboot node function in dashboard if it is technically possible.

Please describe your use case for this integration and alternatives you've tried:
I've usually used the OTA function to get the node to restart if I need it to, but a reboot function would be better.
