Object storage proxy (#11357)

Browse Source 
Service targeted for storing and retrieving LFC prewarm data.
Can be used for proxying S3 access for Postgres extensions like
pg_mooncake as well.

Requests must include a Bearer JWT token.
Token is validated using a pemfile (should be passed in infra/).

Note: app is not tolerant to extra trailing slashes, see app.rs
`delete_prefix` test for comments.

Resolves: https://github.com/neondatabase/cloud/issues/26342
Unrelated changes: gate a `rename_noreplace` feature and disable it in
`remote_storage` so as `object_storage` can be built with musl
