CLI: add notmuch-config support for named queries

Most of the infrastructure here is general, only the validation/dispatch
is hardcoded to a particular prefix.

A notable change in behaviour is that notmuch-config now opens the
database e.g. on every call to list, which fails with an error message
if the database doesn't exit yet.
