Motivation: See the linked issues for details. The most notable user-relevant bits are: - This cleans up the `MountedSSHStore`: decomposed into its orthogonal parts - This brings us pretty close to being able to then implement a JSON-based config. - Store query parameters can be JSON - Stores can entirely be specified via JSON objects, but this is not yet hooked up to anything. Also behind the scenes have these benefits: 1. The docs are moved out of the headers, good for less rebuilding when they changes 2. Stores are always constructed from store configs 3. Use JSON, avoid custom serializers Context: Part of #11106 Co-Authored-By: Robert Hensing <robert@roberthensing.nl> Co-authored-by: Sergei Zimmerman <145775305+xokdvium@users.noreply.github.com>
