[#4185] SpdyHttpEncoder fails to convert HttpResponse to SpdyFrame

Browse Source 
Motivation:

When SpdyHttpEncoder attempts to create an SpdyHeadersFrame from a HttpResponse an IllegalArgumentException is thrown if the original HttpResponse contains a header that includes uppercase characters. The IllegalArgumentException is thrown due to the additional validation check introduced by #4047.

Previous versions of the SPDY codec would handle this by converting the HTTP header name to lowercase before adding the header to the SpdyHeadersFrame.

Modifications:

Convert the header name to lowercase before adding it to SpdyHeaders

Result:

SpdyHttpEncoder can now convert a valid HttpResponse into a valid SpdyFrame
