ActiveSupport.run_load_hooks(*, self) => Metasploit::Concern.run(self)

MSP-10037

Convert older, explict `ActiveSupport.run_load_hooks` calls to
`Metasploit::Concern.run` calls.
Add Metasploit::Concern.run(self) to models

MSP-10039

Add `Metasploit::Concern.run(self)` calls to models which were lacking
it.  Most importantly, add it to the
MetasploitDataModels::Search::Visitor::* models so that new classes can
be visited.
Use 'Metasploit::Concern.run' shared examples in specs

MSP-10037
Bump version so prerelease version can be released

MSP-10037
Merge pull request #61 from rapid7/feature/10037/metasploit-concern
