- feature: add python code runner api

[agallardol]

Status: It's s working progress. Right now we have a working version with no auth layer.

Challenges:

• Currently it's using a hidden webview that execute the python code in a Web Worker. It seems hidden web processes, specially web workers receives a lot of throttling while they are in background/non-focused mode.
  We need to investigate this (more info at dcSpark slack)

CURL example:

Request

curl -X "POST" "http://127.0.0.1:11436/run-code"
-H 'Content-Type: application/json'
-d $'{
"configurations": "null",
"code": "print('hello world')",
"parameters": "null"
}'
