Close this issues page, point to Metasploit-Framework's issues

[todb-r7]

Since 614b0aa in 2011, we've seen one issue filed against this repo.

I suspect that there is no case anyone would want to file a bug here -- they really want to file a bug over on rapid7/metasploit-framework.

Seems like the CONTRIBUTING.md page should point people there, and disable issues.

I bet this goes for a few of the support gems. I'm happy to sort this out. About the only support gem that gets issues with any frequency is rapid7/meterpreter.

I guess the only time submitting an issue here would ever make sense is if the use-case in question was using metasploit-model in something other than metasploit-framework or pro, but that may never happen.
