Registering back to initializing

Fix a bug in which if the node attributes/meta changed, we would
re-register the node in status initializing. This would incorrectly
trigger the client to log that it missed its heartbeat.
It would change the status of the Node to initializing until the next
heartbeat occured.

Non-locked accessors to common Node fields
...
This PR removes locking around commonly accessed node attributes that do
not need to be locked. The locking could cause nodes to TTL as the
heartbeat code path was acquiring a lock that could be held for an
excessively long time. An example of this is when Vault is inaccessible,
since the fingerprint is run with a lock held but the Vault
fingerprinter makes the API calls with a large timeout.
