Syslog format by default

[gregshep]

Overall Review of Changes:
Use syslog format for one line per timestamp for better external logger support (i.e. Splunk)

Issue Fixes:
By default, aide logs are multi-line without timestamp making external logger parsing complex.

Enhancements:
Each log output line has a timestamp

How has this been tested?:
Tested locally with an instance using this repo, verified output logs are syslog format.

@gregshep,
Thanks for setting up this PR. one thing that will need to be updated before we can merge this in is the DCO setup. For us to merge it will need to have all commits GPG signed and have the signed-off by added. Once those are done the DCO check will show a green check and I can then work on merging the work.
