3dc98c8ce3 Keep quic protocol headers only between one hop 
Removing quic protocol headers from being persisted during proxy requests.
Not removing them could lead to the client attempting to connect to the wrong port.
This makes the quic headers consistent with other protocol headers.

Working on a fix for proxy related to setting Host header (cf. #874) 
Also see
https://forum.caddyserver.com/t/caddy-0-9-beta-version-available-updated-beta-2/146/29?u=matt
which has another account of strange proxy behavior; I think this
resolves that.

a798e0c951 Refactor how caddy.Context is stored and used 
- Server types no longer need to store their own contexts; they are
  stored on the caddy.Instance, which means each context will be
  properly GC'ed when the instance is stopped. Server types should use
  type assertions to convert from caddy.Context to their concrete
  context type when they need to use it.
- Pass the entire context into httpserver.GetConfig instead of only the
  Key field.
- caddy.NewTestController now requires a server type string so it can
  create a controller with the proper concrete context associated with
  that server type.

Tests still need more attention so that we can test the proper creation
of startup functions, etc.

a50462974c Refactor and clean up policy code 
This commit shouldn't change any behavior. It is simply a cleanup of
the different proxy policies. It also adds some comments explaining the
sampling method used, since on first inspection it might not appear to
be a uniformly random selection.

fee4890e94 Balance round robin evenly when some hosts are down (#880) 
* Balance round robin evenly when some hosts are down

Before, when load balancing across multiple hosts, if a host went down
then the next host in line would be sent a double share of requests.
This is because the round robin counter was only incremented once per
request, regardless of the health of the selection. If current
selection was unhealthy then the policy would advance to the next host,
but this would not be reflected in the policy counter. To fix this, the
counter is now incremented for every attempted host.

This commit adds a test case that identifies the issue, and a fix.

* Make robin counter private

* Use a mutex to sync round robin selection
