463c9d9dd2 Fix data race for max connection limiting in proxy directive. (#1438) 
* Fix data race for max connection limiting in proxy directive.

The Conns and Unhealthy fields are updated concurrently across all active
requests.  Because of this, they must use atomic operations for reads and
writes.

Prior to this change, Conns was incremented atomically, but read unsafely.
Unhealthly was updated & read unsafely.  The new test
TestReverseProxyMaxConnLimit exposes this race when run with -race.

Switching to atomic operations makes the race detector happy.

* oops, remove leftover dead code.

ecf852ea43 proxy: fix TestReverseProxy failure on go tip (#1360) 
Because of this commit(6e36811c37399d60cbce587b7c48e611009c5aec) on go tip,
it will probe the request's body to determine whether to use chunked transfer
encoding which trailers depend on it.
So we just offer a non empty body to make trailers work.

fix issue #1359

a3aa414ff3 Fixed HTTP/2 support for the proxy middleware (#1300) 
* Fixed HTTP/2 support for the proxy middleware

http.Transport instances whose TLSClientConfig, Dial, or DialTLS field
is non-nil will be configured without HTTP/2 support by default.

This commit adds the proper calls to http2.ConfigureTransport()
everywhere a http.Transport is created and thus fixes HTTP/2 in the
proxy middleware whenever insecure_skip_verify or keepalive is provided.

* Added HTTP/2 support check to TestReverseProxyInsecureSkipVerify

b783caaaed Filter empty headers (#1239) 
* Filter empty headers

Some web servers (e.g. Jetty 9.3) don’t like HTTP headers with empty values. This commit filters header replacements with zero length.

* Extend tests to verify removal of empty headers

* Handle add-header case

* Change - Use short variable assignment
