In some cases proxy should sanitize incoming headers. --drop-header and $DROP_HEADERS set list of headers (keys) and those headers removed from the request.
This is an attempt to address #108
Instead of dedicated support of header`s removal it allows to return a flag indicating plugin's full control over headers. With this flag set, the conductor won't mix response headers with originals but rather will count on a plugin to provide all the headers.
