As of now, procedures, hooks and crons have to be define like this:

from platypush import procedure

@procedure
def some_procedure(**context):
  ...

That's because there's a bunch of stuff that we passed on the context (response of the previous request, environment variables, results of previous key-value parsing operations etc.)

We should also allow more compact definitions:

from platypush import procedure, when

@procedure
def some_procedure():
  ...

@when(SomeEvent)
def on_some_event(event):
  ...

@when(SomeOtherEvent)
def on_some_other_event():
  ...

The caller should inspect the signature of the function and pass the arguments according to what it needs.
