Option to not escape control characters

[thom-nic]

I just ran into an issue where papertrail was getting escaped ANSI color sequences like this:

The solution I got from their support was to add this to the ryslog conf, which worked!
$EscapeControlCharactersOnReceive off
After:

I don't know if that's safe to add by default or if you can add an ansible variable that toggles this setting but either one of those options would be great. Thanks!

@thom-nic , thanks! ill look into it tomorrow.
Sorry for the delay.

No problem! I should have mentioned, I ran into this on a stock Ubuntu Server 14.04 image with the default rsyslog setup. So I have no idea how often this might crop up for other people but I don't think I was doing anything exceptional.

@thom-nic
I'm not quite convinced that papertrail role should take care of rsyslog configuration that is not really related to papertrail service, but i've added support for it for now.

I'll keep that issue open in case other people would like to add their opinion.
