Fixes#1628
- add [`comfy_table`](https://github.com/Nukesor/comfy-table/tree/main) and use it to construct table for `pg list` CLI command

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
Now princeple is following: acceptor threads (libpq and http) error will
bring the pageserver down, but all per-tenant thread failures will be treated
as an error.
A new `get_lsn_by_timestamp` command is added to the libpq page service
API.
An extra timestamp field is now stored in an extra field after each
Clog page. It is the timestamp of the latest commit, among all the
transactions on the Clog page. To find the overall latest commit, we
need to scan all Clog pages, but this isn't a very frequent operation
so that's not too bad.
To find the LSN that corresponds to a timestamp, we perform a binary
search. The binary search starts with min = last LSN when GC ran, and
max = latest LSN on the timeline. On each iteration of the search we
check if there are any commits with a higher-than-requested timestamp
at that LSN.
Implements github issue 1361.
* Traverse frozen layer in get_reconstruct_data in reverse order
* Fix comments on frozen layers.
Note explicitly the order that the layers are in the queue.
* Add fail point to reproduce failpoint iteration error

Now proxy binary accepts `--auth-backend` CLI option, which determines
auth scheme and cluster routing method. Following backends are currently
implemented:
* legacy
old method, when username ends with `@zenith` it uses md5 auth dbname as
the cluster name; otherwise, it sends a login link and waits for the console
to call back
* console
new SCRAM-based console API; uses SNI info to select the destination
cluster
* postgres
uses postgres to select auth secrets of existing roles. Useful for local
testing
* link
sends login link for all usernames
* `cloud::legacy` talks to Cloud API V1.
* `cloud::api` defines Cloud API v2.
* `cloud::local` mocks the Cloud API V2 using a local postgres instance.
* It's possible to choose between API versions using the `--api-version` flag.
This is needed to forward the `ClientKey` that's required
to connect the proxy to a compute.
