Fix broken load-session utility and change it to load and save a session

Rename run-session-tests.sh script to load-save-session.sh and make it operate on
only a single session and add a separate load-save-session-collection.sh script

Add --massif option to load-save-session.sh script

Rename some poorly named variables and add some documentation to the
load-save-session.sh script
