Astroid hook for the Hypothesis library.

Without this hook pylint reports no-value-for-parameter for use of strategies defined using the @hypothesis.strategies.composite decorator. For example:

from hypothesis import strategies as st

@st.composite def a_strategy(draw):

return draw(st.integers())

a_strategy()

Function is_decorated_with_st_composite Return True if a decorated node has @st.composite applied.
Function remove_draw_parameter_from_composite_strategy Given that the FunctionDef is decorated with @st.composite, remove the first argument (draw) - it's always supplied by Hypothesis so we don't need to emit the no-value-for-parameter lint.
