MSP-11671
Add command line option --defer-module-loads to msfconsole. It will
stop `Msf::Ui::Console::Driver` from calling
`framework.modules.init_module_paths` AND
`framework.modules.refresh_cache_from_database`. This flag is only
meant to speed up msfconsole boot when modules do not need to accessed,
such as during cucumber testing of command help or command line options.
