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] Add SCRAM auth
* [proxy] Implement some tests for SCRAM
* Refactoring + test fixes
* Hide SCRAM mechanism behind `#[cfg(test)]`
Currently we only use it in tests, so we hide all relevant
module behind `#[cfg(test)]` to prevent "unused item" warnings.
* [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).

This change causes writer halves of a TLS stream to always flush after a
portion of bytes has been written by `std::io::copy`. Furthermore, some
cosmetic and minor functional changes are made to facilitate debug.
- 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.
