modules direct share menu items

closes: ADMIN-2781
flag: direct_share

test plan:
- NOTE: the modules page is cached, so you might have to wait a minute
  or refresh a couple times in order for changes to show up after you
  change the flag.
- teacher view of modules should have new menu items only when the
  feature flag is on
- This applies to both modules and module items
- Should also work when modules is the course home page
