Orbit objects cannot be unpickled #369

🐞 Problem

(Reported by Joan Fort Alsina https://groups.io/g/poliastro-dev/message/47)

When attempting to do a propagation inside a multiprocessing.Pool, a weird RecursionError is returned. For example, with this script:

from astropy import units as u
from astropy import time

from poliastro.bodies import Earth
from poliastro.twobody import Orbit

import multiprocessing as mp

def create_constellation(epoch):
    a = 1150.0 * u.km
    ecc = 0.0*u.one
    inc = 53.0*u.deg
    argp = 0.0*u.deg
    return [Orbit.from_classical(Earth, a, ecc, inc, 11.25*plane*u.deg, argp, 7.2*sat*u.deg, epoch)\
                for plane in range(0,32) for sat in range(0,50)]


def propagate(sat):
    return sat.propagate(10 * u.min)       

if __name__ == '__main__':    
    epoch = time.Time("2018-04-25 11:00")    
    spx = create_constellation(epoch)
    
    p = mp.Pool(4)
    result = p.map(propagate,spx)
    p.close()
    p.join()

This is the failure:

RecursionError: maximum recursion depth exceeded while calling a Python object

Debugging this is hard. By adding some dirty lines to Orbit:

Which leads to this documentation https://docs.python.org/3/library/pickle.html#pickling-class-instances

🎯 Goal

Being able to run several propagations in parallel using multiprocessing is essential, since it allows the users to easily analize satellite constellations.

💡 Possible solutions

I will try to fix this by making Orbit objects pickeable.
