The `framework` from 'Msf::Simple::Framework' shared context is not
guaranteed to make threads with `framework.threads` anymore, so the
cleaner shouldn't allows be present in 'Msf::Simple::Framework'.
MSP-11147
Extract from 'Msf::Simple::Framework' the `after(:each)` that kills and joins
threads from `framework.threads` into 'Msf::Framework#threads cleaner`.

For 'Msf::Simple::Framework#modules loading''s load_and_create_modules,
don't require `:ancestor_reference_names` when the `:module_type` is not
payload as the one ancestor reference name will be the same as
`:reference_name`.
MSP-11130
'Msf::Simple::Framework#modules loading' defines
`#load_and_create_module`, which takes the :ancestor_reference_names,
:modules_path, :module_type, and :reference_name of the module whose
ancestors to load and the reference name to create. A default modules
path, the first 'modules' path for the Rails application is available in
in the `#modules_path` let.

Move Msf::DBManager#import_msf_xml into
Msf::DBManager::ImportMsfXml#import_msf_xml and include
Msf::DBManager::ImportMsfXml to cut down size of the infamous db.rb.
Break up #import_msf_xml to have separate methods for parsing web_forms,
web_pages, and web_vulns. The method for
web_vulns, #import_msf_web_vuln_element is needed so that it can be overridden in
Pro to handle the Pro-only changes to Mdm::WebVuln.
