Only inject @Parameter-created variables in the Action itself

Icann reports have 3 parameter-provided injections:

- yearMonth
- subdir
- reportType

We move all of them away from the "inner classes" and only @Inject them in the Actions themselves.

This has 2 benefits:
- it's much clearer what all the parameter inputs of the Actions are
- the "inner injected classes" don't assume anything about the Action that uses them - they will work just as well for JSON actions as for "regular" actions.
