intermine and Python 3.10

[jburel]

Using the Python API with Python 3.10 leads to the following error

from intermine.webservice import Service
Traceback (most recent call last):
  File "/Users/jmarie/opt/anaconda3/envs/intermine-test/lib/python3.10/site-packages/intermine/webservice.py", line 9, in <module>
    from urlparse import urlparse
ModuleNotFoundError: No module named 'urlparse'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/jmarie/opt/anaconda3/envs/intermine-test/lib/python3.10/site-packages/intermine/webservice.py", line 16, in <module>
    from collections import MutableMapping as DictMixin
ImportError: cannot import name 'MutableMapping' from 'collections' (/Users/jmarie/opt/anaconda3/envs/intermine-test/lib/python3.10/collections/__init__.py)

No problem with Python version <3.10

We are also having issues due to this, which #97 would fix.
