This PR refactors
FilterManager
intoSharedFilterChain
, which instead of using message passing, usesArcSwap
to provide a updatable handle to a filter chain. This simplifies a lot of the communication infrastructure as we can just passSharedFilterChain
directly around instead, update it as needed, and it will be updated on subsequent loads. This also makes it easy to inspect the current state of the filter chain.
