MINOR: quic: Add a fake congestion control algorithm named "nocc"

This algorithm does nothing except initializing the congestion control window
to a fixed value. Very smart!

Modify the QUIC congestion control configuration parser to support this new
algorithm. The congestion control algorithm must be set as follows:

     quic-cc-algo nocc-<cc window size(KB))

For instance if "nocc-15" is provided as quic-cc-algo keyword value, this
will set a fixed window of 15KB.
