* service was running wrong RunOnce method
* after doing integration with GC sender we concluded that we don't
need special flag "gc-sender" to be uploaded as its safe to consume
partial results by GC senger. This part was removed.
* prefix format for moving data after error was unified with GC
sender

Implement a new service to read retain filter from a bucket and
send them out to storagenodes.
This allows the retain filters to be generated by a separate command on
a backup of the database.
Paralellism (setting ConcurrentSends) and end-to-end garbage collection
tests will be restored in a subsequent commit.
