Kirill Bulatov d8939d4162 Move walreceiver start and stop behind a struct (#3973) ...

The PR changes module function-based walreceiver interface with a
`WalReceiver` struct that exposes a few public methods, `new`, `start`
and `stop` now.

Later, the same struct is planned to be used for getting walreceiver
stats (and, maybe, other extra data) to display during missing wal
errors for https://github.com/neondatabase/neon/issues/2106

Now though, the change required extra logic changes:

* due to the `WalReceiver` struct added, it became easier to pass `ctx`
and later do a `detached_child` instead of

https://github.com/neondatabase/neon/blob/bfee4127014022a43bd85bccb562ed4bc62dc075/pageserver/src/tenant/timeline.rs#L1379-L1381

* `WalReceiver::start` which is now the public API to start the
walreceiver, could return an `Err` which now may turn a tenant into
`Broken`, same as the timeline that it tries to load during startup.

* `WalReceiverConf` was added to group walreceiver parameters from
pageserver's tenant config
