gssapi: document ZMQ_GSSAPI_PRINCIPAL as optional

is optional.

-----------------------
A socket using GSSAPI can be either client or server, but not both.
To become either a GSSAPI client or server, the application sets the
ZMQ_GSSAPI_PRINCIPAL option to provide the socket with the name of the principal
for whom GSSAPI credentials should be acquired.
To become a GSSAPI server, the application sets the ZMQ_GSSAPI_SERVER
option on the socket.
To become a GSSAPI server, the application additionally sets the
ZMQ_GSSAPI_SERVER option on the socket.
To become a GSSAPI client, the application sets the ZMQ_GSSAPI_SERVICE_PRINCIPAL
option to the name of the principal on the server to which it intends to
connect.
To become a GSSAPI client, the application additionally sets the
ZMQ_GSSAPI_SERVICE_PRINCIPAL option to the name of the principal of the server
to which it intends to connect.
On client or server, the application may additionally set the
ZMQ_GSSAPI_PRINCIPAL option to provide the socket with the name of the
