v7 systems.

Change the default transport for rsyslog v5 remote syslog message
delivery to UDP.  This will result in message loss when the remote
syslog server is unavailable, but it avoids the complexities of the v5

default format that pulls all template and output configuration from
the rsyslog.d fragments directory.  Current default behavior is not
changed for now.

Add v5 and v7 fragments for default templates and output.  New
fragments to support a more complete time format.
