rpk: print loaded node configuration

[r-vasquez]

Who is this for and what problem do they have today?

Users who want to use rpk to query what node configuration properties are loaded in the node.

See this community slack thread as an example: https://redpandacommunity.slack.com/archives/C01AJDUT88N/p1675617152235159?thread_ts=1674497965.762759&cid=C01AJDUT88N

What are the success criteria?

Use rpk to print the loaded configuration, a wrapper around the Admin API call:

$ curl localhost:9644/v1/node_config

Why is solving this problem impactful?

Consistency, we have a similar command for cluster properties: rpk redpanda admin config print
