0e1bd57c53 Add WAL offloading to s3 on safekeepers.
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

6cb14b4200 Optionally remove WAL on safekeepers without s3 offloading.
And do that on staging, until offloading is merged.

8b9d523f3c Remove old WAL on safekeepers.
Remove when it is consumed by all of 1) pageserver (remote_consistent_lsn) 2)
safekeeper peers 3) s3 WAL offloading.

In test s3 offloading for now is mocked by directly bumping s3_wal_lsn.
