Test the following paths in order and only return them if the path
exists:
1. MSF_DATABASE_CONFIG environment variable
2. ~/.msf4/database.yml
3. <project>/config/database.yml
MSP-10848
Use these locations, in order for
Metasploit::Framework::Application.config.paths['config/database']:
1. MSF_DATABASE_CONFIG environment variable
2. ~/.msf4/database.yml (if it exists)
3. config/database.yml

Other railties, like jquery-rails, need 'action_view/railtie', but don't
require it themselves, so require it explictly in
`config/application.rb` to prevent msfconsole boot errors.

Extra config and initializers that can we shared between
Metasploit::Framework::Application and the future
Metasploit::Framework::Engine. Move the default encoding setup from
lib/msf/sanity.rb to a before_initialize callback for the shared config
so that gems, like gherkin that depend on the utf-8 default internal
encoding can be loaded.
MSP-9606
Catch LoadError in config/application.rb when trying to require
'active_record/railtie` so that end-users can run without any of the
database gems installed. NOTE: you can't run in the development or
test environment without the database because factory_girl needs
ActiveRecord.

In order to support Metasploit::Credential correctly,
metasploit-framework needs to support Metasploit::Concern, which does
all its magic using a Rails::Engine initializer, so the easiest path is
to make metasploit-framework be able to use Rails::Engines. To make
Rails::Engine use Rails::Engine, make a dummy Rails::Application
subclass so that all the initializers will be run when anything requires
msfenv.
