* `control_plane` crate (used by `neon_local`) now parses an `auth_enabled` bool for each Safekeeper
* If auth is enabled, a Safekeeper is passed a path to a public key via a new command line argument
* Added TODO comments to other places needing auth
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.

* There is no auth in Safekeeper HTTP at all currently,
so simply calling `check_permission` is not enough.
* There are no checks of Safekeeper still working with the data,
as "still working" is burry now: a timeline may be "active"
while there are no compute nodes and all data is propagated.
* Still, callmemaybe is deactivated, and timeline is removed from the
internal map. It can easily sneak back in case of race conditions
and implicit creations, though.
Make it remember when timeline starts in general and on this safekeeper in
particular (the point might be later on new safekeeper replacing failed one).
Bumps control file and walproposer protocol versions.
While protocol is bumped, also add safekeeper node id to
AcceptorProposerGreeting.
ref #1561
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.
