[Plan] Making a full release of Lazy Mega Menu

There is nothing that frustrates me more in the issue queue than a module that never makes it to a full release. So, here are the tasks required to move to each stage, with status...

Alpha release

#2881914: Create Project info page and README file - should be consistent
#2881915: PHP Coding Standards and Warnings
#2881922: How can we keep the mega-menu content items and menu items in sync?
#2881936: Remove deprecated code
#2881919: Redirect to the list of mega-menu content after creating a new mega-menu content entity

Beta release

#2881949: Create documentation to use
#2881917: Provide some really basic positioning styling
#2881943: Consider whether mandating the menu triggering the mega menu has subitems is reasonable
#2881953: Ensure /mega-menu-content is cacheable

Full release
