cli: Warn user about implicit seeding policy

To prepare for future changes, warn users if their config file currently
does not explicitly specify a default seeding policy.

Because there are now potentially multiple warnings generated that all
relate to the configuration file, group these together and adjust the
wording to be more uniform.
