[conntrackd] Support Debian/Ubuntu and capture conntrack info

[hillpd]

The plug-in checks for "conntrack-tools" but doesn't capture any debug information from the conntrack utility. On Debian/Ubuntu the tools package is simply named "conntrack" which should be included.

Recommend adding the following command output:
conntrack -L -o extended
conntrack -S

"conntrack" is a separate package (on Ubuntu), so perhaps the cleanest way forward is to add a plugin for conntrack itself, and capture -L, -S, etc, via the separate plugin.

@TurboTurtle I'm thinking just add to current plugin makes sense. It could also be separated as two plugins conntract and contractd (On ubuntu conntract is supported, while conntractd is not).

Wow, this excerpt from the manual really hits the nail on the head

Although the name of both tools is very similar - and you can blame me for that, I'm not a marketing guy - they are used for very different tasks.

At any rate, since both utilities are at least logically coupled together I'd be in favor of adding this to the current plugin, rather than splitting out a new one.

sosreport is fault tolerant (if cmd doesn't exist, it will continue) so I personally would simply add the conntrack command in the current plugin with the conntrack package name as one of the possible triggers. And maybe rename the plugin from conntrackd.py to conntrack.py to make it more connection tracking specifics ?

+1 to have just one plugin, and rename it to contrack.
