nodebuilder/node: `Init` should also generate and save node ID and JWT secret

[renaynay]

Init initialises the node directory, but is still missing some components:

• Node ID
• JWT secret

Users should be able to run celestia <node_type> init and for all keys to be present such that they can

• know their own peerID
• generate jwt tokens before the node is started.

Or we should remove init altogther in favor of lazy init from start

I would prefer not to remove it before doing a bit of research with node operators to see how many actually prefer the initialisation step to be separate.

@renaynay @Wondertan Hi! I opened a PR (#4232) that adds Node ID and JWT secret generation as suggested here. Let me know if there’s anything missing or that needs adjustment. Thanks!

That can be done as a separate issue.

We should make sure that the user has access to this data and isn't just a one-off

Just that we should store the node id and jwt secret
