dbus: Add Details to org.gnome.OnlineAccounts.Ticketing

This commit adds a new "details" variant for attaching metadata
about tickets getting requested via the ticketing interface.

This will give the kerberos account provider a place to tuck away
kerberos-specific preauthentication configuration for the tickets
associated with smartcard backed kerberos accounts.
