wrap response.headers key with HeaderKey

[nggit]

Store response headers original casing in an interning table.

key = HeaderKey(b'Content-Type')

print(key)  # b'content-type'
print(key.name)  # b'Content-Type'

interning table is global (class-level), unbouded, but HeaderKey() is meant to be used for response header names (server-generated). You must not response.set_header(name, value) with a client-generated name.
