MISP_2_0 analyzer throws error when executed on an IP observable inside Cortex docker image

Bug

Work Environment

Problem Description

Not sure if it is caused by the Cortex docker image or the analyzer's code, but when the latest MISP_2_0 analyzer is run on an IP, Cortex chokes with the following traceback:

Invalid output
WARNING [__init__.py:49 - <module>() ] Unable to load pymisp properly: No module named enum
Traceback (most recent call last):
  File "MISP/misp.py", line 80, in <module>
    MISPAnalyzer().run()
  File "MISP/misp.py", line 29, in __init__
    proxies={'http': self.http_proxy, 'https': self.https_proxy})
  File "/opt/Cortex-Analyzers/analyzers/MISP/mispclient.py", line 59, in __init__
    self.misp_connections.append(pymisp.PyMISP(url=server,
AttributeError: 'module' object has no attribute 'PyMISP'

Steps to Reproduce

1. Deploy Cortex as a docker container or Swarm service
2. Supply latest analyzers as a docker volume
3. Use MISP_2_0 analyzer on an IP observable

Possible Solutions

Perhaps a dependency issue in Cortex docker image for PyMISP? The only place it imports from enum import Enum is here
