MXS-421 Add maxscale::event concept

Browse Source 
MaxScale now defines events for which the syslog
facility and level can explicitly be defined by the
administrator. Currently there is only one such
event, namelt AUTHENTICATION_FAILURE.

In a subsequent commit, config.cc will be modified so
that event-related configuration parameters are passed
to event::configure() and in another subsequent commit
the authenticators will be modifed to use this mechanism.

In practice a line like:

   MXS_WARNING("%s: login attempt for user '%s'@[%s]:%s, "
               "authentication failed.",
               dcb->service->name, client_data->user,
               dcb->remote, dcb->path);

will be changed to

    MXS_LOG_EVENT(event::AUTHENTICATION_FAILURE,
                  "%s: login attempt for user '%s'@[%s]:%s, "
                  "authentication failed.",
                  dcb->service->name, client_data->user,
                  dcb->remote, dcb->path);
