Håkon Hægland f94553c5a7 Python bindings for the blackoil simulator.
A simplified version of PR #2518 that uses a deck filename to construct
the simulator.

After private discussion with @joakim-hove it was decided that the
construction of the blackoil simulator from Python using deck,
ecliseState, schedule and summaryConfig as constructor arguments from
\#2518 should be replaced by a constructor taking only the deck filename
as parameter.

A rewrite of the Python bindings for the blackoil simulator using
pybind11 as introduced in PR #2127. The new version uses the
refactored flow.cpp introduced in PR #2516 and thus avoids duplication
of the code in simulators.cpp.

This PR will be the starting point for implementing the Python bindings
introduced in PR #2403.
