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.
* [proxy] Propagate most errors to user
This change enables propagation of most errors to the user
(e.g. auth and connectivity errors). Some of them will be
stripped of sensitive information.
As a side effect, most occurrences of `anyhow::Error` were
replaced with concrete error types.
* [proxy] Box weighty errors
This change makes most parts of the code asynchronous, except
for the `mgmt` subsystem (we're going to drop it anyway).

Do it separately with SafekeeperPostgresCommand enum as a result. Since query is
always C string, switch postgres_backend process_query argument from Bytes to
&str.
Make passing ztli/ztenant id in safekeeper connection string optional; this is
needed for upcoming intra-safekeeper heartbeat cmd which is not bound to any
timeline.
- perform checkpoint for each tenant repository.
- wait for the completion of all threads.
Add new option 'immediate' to 'pageserver stop' command to terminate the pageserver immediately.
Commit message copied below:
* Allow LeSer/BeSer impls missing Serialize/Deserialize
Currently, using `LeSer` or `BeSer` requires that the type implements
both `Serialize` and `DeserializeOwned`, even if we're only using the
trait for one of those functionalities.
Moving the bounds to the methods gives the convenience of the traits
without requiring unnecessary derives.
* Remove unused #[derive(Serialize/Deserialize)]
This should hopefully reduce compile times - if only by a little bit.
Some of these were already unused (we weren't using LeSer/BeSer for the
types), but most are have *become* unused with the change to
LeSer/BeSer.

This patch has been extracted from #348, where it became unnecessary
after we had decided that we didn't want to measure anything inside
PostgresBackend.
IMO the change is good enough to make its way into the codebase,
even though it brings nothing "new" to the code.
The metrics are served by an http endpoint, which
is meant to be spawned in a new thread.
In the future the endpoint will provide more APIs,
but for the time being, we won't bother with proper routing.
