refs #7753 This PR is step (1) of removing sync walredo from Pageserver. Changes: * Remove the sync impl * If sync is configured, warn! and use async instead * Remove the metric that exposes `kind` * Remove the tenant status API that exposes `kind` Future Work ----------- After we've released this change to prod and are sure we won't roll back, we will 1. update the prod Ansible to remove the config flag from the prod pageserver.toml. 2. remove the remaining `kind` code in pageserver These two changes need no release inbetween. See #7753 for details.

(1) rip out sync impl, make config setting still accepted but a no-op, warn if config setting is != async
(2) release, make sure we won't roll back
(3) remove the field from production pageserver.toml (Ansible change)
(4) remove config flag parsing code
(5) release; if we have to roll back PS version, the field will not be in PS toml; that's fine cuz (1) changed the default to async
Impl
