[PATCH 14/36] cli/dump: convert to new config framework

[David Bremner <david@tethera.net>]

This conversion is trivial because the only configuration information
accessed by dump is that stored in the database (in order to dump
it). We do need to be careful to keep the write lock on the database
to ensure dump consistency.
