Use ActiveRecord::Migrator  multiple migrations paths support

[#44034071]

ActiveRecord::Migrator has a class attribute, migrations_paths,
specificially for storing a list of different directories that have
migrations in them.  ActiveRecord::Migrator.migrations_paths is used in
rake db:load_config, which is a dependency of db:migrate, etc. that is
passed to ActiveRecord::Migrator.migrate.  Since migrate supports an
array of directories, and not just a single directory, there is no need
to merge all the migrations paths into one temporary directory as was
previously done.
Correct return type of Msf::DBManager#migrate.

This update to Armitage improves its responsiveness when connected
to a team server over a high latency network. This update also adds
a publish/query/subscribe API to Cortana.

Apparently, my last update came from the future. This modification
to that future update fixes an oversight preventing Armitage from
connecting to its collaboration server because it would report the
wrong application.
