Improve typing in user_directory files (#10891)

Browse Source 
* Improve typing in user_directory files

This makes the user_directory.py in storage pass most of mypy's
checks (including `no-untyped-defs`). Unfortunately that file is in the
tangled web of Store class inheritance so doesn't pass mypy at the moment.

The handlers directory has already been mypyed.
