Propagate remote_consistent_lsn to safekeepers.

Browse Source 
Change meaning of lsns in HOT_STANDBY_FEEDBACK:
flush_lsn = disk_consistent_lsn,
apply_lsn = remote_consistent_lsn
Update compute node backpressure configuration respectively.

Update compute node configuration:
set 'synchronous_commit=remote_write' in setup without safekeepers.
This way compute node doesn't have to wait for data checkpoint on pageserver.
This doesn't guarantee data durability, but we only use this setup for tests, so it's fine.
