Pavel Emelyanov 2b63c4c16f gossiper, main: Turn init_gossiper into get_seeds_from_config
Looking into init_gossiper() helper makes it clear that what it does
is gets seeds, provider and listen_address from config and generates
a set of seeds for the gossiper. Then calls gossiper.set_seeds().

This patch renames the helper into get_seeds_from_config(), removes
all but db::config& argunebts from it and moves the call to set_seed()
into main.
