Jon Siwek e34f6d9e3b Enable GridFTP detection by default. Track/log SSL client certs.
In the *service* field of connection records, GridFTP control channels
are labeled as "gridftp" and data channels as "gridftp-data".

Added *client_subject* and *client_issuer_subject* as &log'd fields to
SSL::Info record.  Also added *client_cert* and *client_cert_chain*
fields to track client cert chain.
