Msf::PayloadSet#add_module does NOT return an annotated module class as
Msf::ModuleSet#add_module does because a payload module is defined as a
ruby Module instead of a ruby Class. Since add_module doesn't always
return an annotated_class, the logic in
Msf::ModuleManager#on_module_load needed to change to NOT use
annotated_class and create #add_module as return [void]. Thus, it is
necessary to pass in all the metasploit module metadata to
Msf::ModuleManager#cache_in_memory instead of assuming they can be
derived from the (payload) Module or (other) Class.
[#47720609]
Msf::ModuleManager#module_info_by_path was not being updated when a
module was loaded, so if a load_module was called again, say during
start up of prosvc, the module would reload even though there was no
change in the file because file_changed? couldn't find an entry for the
module's path in module_info_by_path.

Even though using Timecop locally on OS X makes the `should == <Time>`
work, it fails on travis-ci, so try using `should
be_within(1.second).of(<Time>)` instead.
