* feat: Remove support for BrowserID
* mark test only functions as such. I think we can drop MapAndThenTrait for more recent implementations of rust.
Closes: SYNC-3684
This is a breaking change. This commit separates syncstorage and tokenserver settings into separate structs that are contained by a parent `Settings` struct. This means that any env vars that hold settings specific to syncstorage (e.g. `SYNC_DATABASE_URL`) have been renamed to `SYNC_SYNCSTORAGE__DATABASE_URL`. Any settings that were moved from the top-level `Settings` struct to the lower level, syncstorage-specific struct will now have a `SYNC_SYNCSTORAGE__` prefix instead of a `SYNC_` prefix.
Closes#1276
