We would like to have separate process/command to collect bloom
filters from source different than production DBs. Such process will
use segment loop to build bloom filters for all storage nodes and
will send it to Storj bucket. This change is extending satellite binary
with appropriete command.
New GC service for collecting bloom filter will be a subsequent
change.
