Suggestion: MD5-hashed config for duplication checking

[exilef]

Hi, I have implemented duplication checking of Experiments in a new class called NoDuplicateExperiment. For this I had to add MD5 computation capabilities. Just as an inspiration..

Example usage:

from sacred.no_duplicate_experiment import NoDuplicateExperiment, DuplicateCheckerMongo
from sacred.observers import MongoObserver

MONGO_HOST = 'localhost'
MONGO_PORT = 27017
MONGO_DB = 'sacred'

exp = NoDuplicateExperiment('test',
  duplicate_checker = DuplicateCheckerMongo(MONGO_HOST, MONGO_PORT, MONGO_DB),
  ignored_params = ('parameter2', ))
exp.observers.append(
  MongoObserver.create(url = '{}:{}'.format(MONGO_HOST, MONGO_PORT), db_name = MONGO_DB))

@exp.config
def config():
  parameter1 = 1
  parameter2 = 'ignored'

@exp.automain
def run(parameter1, parameter2):
  return parameter1 + 1

Coverage decreased (-0.4%) to 83.54% when pulling c8fab79 on exilef:master into 40ac2bc on IDSIA:master.

Reopening, because this is a quite useful start for duplicate detection. I am not sure how I feel about having a separate experiment class, though. It seems more useful to have a flag that prevents starting a duplicate.

I have this in place and it works well.
