symphony/runtime: add simulation executor callbacks, rework simulation executor, command executor and output handling

- import errors
- simulators being inserted into dependency topology multiple times
- some uninitialized variables
- missing or wrong arguments in function calls

orchestration/instantiation/base: refactor dependency graph stuff into its own module and add separation between proxy and simulator

orchestration/instantiation/get_socket(): rename to update_get_socket() since function has side-effects

pyexps/minimal_net_dist.py contains defines an experiment using the new interface

Otherwise components is not set when deserializing using fromJSON, so
that accessing components will fail subsequently.

Additionally, add helper functions for the conversion of the
parameters dict to and from JSON.

symphony/orchestration + symphony/runtime: users can specify artifact paths on instantiation to create artifacts after simulation

Should be explicitly created by the runtime later and set.

Do not assume that everything is running from the repo. Finding things
relative to the python script paths is also broken once packages get
installed via pip etc. For now just default to having SimBricks under
/simbricks or else this has to be set in the environment.
