Deprecating the Python bindings

[Andrew Schwartzmeyer]

Hi all,

There are two parallel efforts underway that would both benefit from 
officially deprecating (and then removing) the Python bindings. The 
first effort is the move to the CMake system: adding support to generate 
the Python bindings was investigated but paused (see MESOS-8118), and 
the second effort is the move to Python 3: producing Python 3 compatible 
bindings is under investigation but not in progress (see MESOS-7163).

Benjamin Bannier, Joseph Wu, and I have all at some point just wondered 
how the community would fare if the Python bindings were officially 
deprecated and removed. So please, if this would negatively impact you 
or your project, let me know in this thread.

Thanks,

Andrew Schwartzmeyer
