Right now, to check if a plugin is functional and what methods it exposes we load the module and test for a given method at run time. This is highly inefficient. It makes far more sense to do this at install time and store the data in the db. I believe we should store a table of methods that each plugin exposes and check that instead. Then, at install time we can test that a) the plugin can be loaded and b) add the available methods to the plugin_methods table.
Test Plan:
1) Apply this patch
2) Restart all the things
3) Run updatedatabase.pl
4) Verify you can use existing plugins
5) Verify you can install new plugins
