feat: Be able to login to bare-metal studio easily.

Updating the documentation and the devstack.py files so that if you're
running bare-metal you can easily setup studio login via the LMS.

I also added the Ports that the various MFEs expect to the runserver
scripts so that it's easier to run those locally as well.

 Run the Platform
 ----------------
 
 First, ensure MySQL, Mongo, and Memcached are running.
 
 Start the LMS::
 
-  ./manage.py lms runserver
+  ./manage.py lms runserver 18000
 
 Start the CMS::
 
-  ./manage.py cms runserver
+  ./manage.py cms runserver 18010
 
 This will give you a mostly-headless Open edX platform. Most frontends have
 been migrated to "Micro-Frontends (MFEs)" which need to be installed and run
