c83242f499 Weaken or remove etags when downstream compression applies 
Allow this as an adjustable setting to preserve etag when
(de)compressing. The default is to weaken etags whenever a compression
module applies.

7003ac34ad Set stale-updating as an explicit CachePhase 
This cache phase indicates when we are serving a stale cache hit, but
there is another request currently updating the asset.

cdefa5c431 Mark the error source from get_http_session() 
Although it is implied that fail_to_connect() errors are already caused
by upstream connections, it is more clear for the user's code inside this callback
by marking the error source in this case.

03bd29044e Always respect_keepalive when releasing http session 
When a user calls `release_http_session` on an http Connector, it is
usually implied that they intend to reuse the underlying connection if
possible. Previously for H1 this involved reaching into the H1 client
Session and calling `respect_keepalive`. The new behavior always
respects keepalive as part of releasing the http session, as it was very
easy to overlook this step and unintentionally disable connection reuse
for H1 sessions.

11863d27a2 Introduce HttpModules to pingora-proxy. 
This feature allows to plug in 3rd party extensions with minimal code
required.

The downstream compression logic is now a module.

Add: a new early_request_filter API to fine tune the behavior of the modules.
Add: a few APIs to write the response with these modules enabled. This
should address issues like compression is not applied to custom
responses.

fa071eb506 Refactor Service API: Arc is no longer needed for apps. 
This change makes a bit cleaner to use the API. It also allows to
modify the application logic before starting the service.

3f682ea37f Add cache_not_modified_filter, handle etag/last-modified 
This filter allows customizing the `ETag`/`Last-Modified` check to see
if the proxy cache can return 304 Not Modified instead of the full
response.

Also flesh out the `ETag`/`Last-Modified` handling in the base
`not_modified_filter` with `If-None-Match` and `If-Modified-Since`.

e811382224 Run upstream_response_filter on 304 from upstream cache revalidation 
Previously only the response_filter would run on revalidated responses
with no way to process the upstream 304.
Also avoid passing through upstream 304 on revalidate
response_cache_filter errors and instead serve from cache. This
simplifies this edge case because it saves us from needing to check
whether the upstream header filter already ran on the 304 later.
