* Fixed#1484
Fixed a nil pointer runtime error in newConnHijackerTransport,
where the access to the TLSClientConfig did not check for nil values.
* Minor improvement to UseInsecureTransport
This prevents overwriting a possibly preexisting TLSClientConfig,
even though only a single field should be changed.
* proxy: use a new context for the outgoing request
fix issue #1345

This issue was caused by connHijackerTransport trying to record HTTP
response headers by "hijacking" the Read() method of the plain net.Conn.
This does not simply work over TLS though since this will record the TLS
handshake and encrypted data instead of the actual content.
This commit fixes the problem by providing an alternative transport.DialTLS
which correctly hijacks the overlying tls.Conn instead.
* 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
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.
