not strictly required, these conversions keep us
up to date with latest rspec conventions and best practices
which will prevent use from having to convert them when they become
deprecated later

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.

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.
[#47720609]
Fix some docs and variable names to make it clearer when methods are
expecting module instance and module classes. Change some 'name'
variables to 'reference_name' since that's the proper terminology.
