Separate task is launched for each timeline and stopped when timeline doesn't need offloading. Decision who offloads is done through etcd leader election; currently there is no pre condition for participating, that's a TODO. neon_local and tests infrastructure for remote storage in safekeepers added, along with the test itself. ref #1009 Co-authored-by: Anton Shyrabokau <ahtoxa@Antons-MacBook-Pro.local>
