Implement ACT_FIELDS_PASSING, test in mongodb

The mongodb test contains only debug printfs.

Example template, inspired by writeMongoDB_msg:

$template MongoTemplate,"%hostname::::sys%%timereported::::time%%timegenerated::::time_rcvd%%msg%%syslogfacility-text::::syslog_fac%%syslogseverity-text::::syslog_server%%syslogtag::::syslog_tag%%programname::::procid%%procid::::pid%%$!foo::::foo%%$!abc::::renamed%"

Note that JSON escaping is actually undesirable in this mode (should it
be silently ignored?), $!all-json doesn't yet work as expected, and all
data is stored as strings.
