lightningd: implement more show commands to reduce listconfigs special casing.
Note that this actually changes listconfigs output for three msat fields, which were not changed with the great msat merge. Since listconfigs isn't actually used by grpc, and the values are always a little vague, I simply changed this. Changelog-Fixed: JSON-RPC: `listconfigs` `htlc-minimum-msat`, `htlc-maximum-msat` and `max-dust-htlc-exposure-msat` fields are now numbers, not strings.
