Change request for new-public-key⁩

[Syther007]

Request changes from card GH-623

To keep Nodes original default behavior, can we set a default for --new-public-key⁩ to be on
Currently --new-public-key⁩ is off by default, causing an issue when trying to rejoin the network.
I feel like keeping your public key the same is for special circumstances and not everyday use.

Request to update the User docs regarding --new-public-key⁩

[possible values: On, Off]

Nodes panic when we use these values given values.
They need to be lower case I.E on, off

Or just make these options case insensitive.
