pymongo has no attribute collection

[uniqueg]

When using PyMongo 4.10.1, apps using FOCA throw the following error:

  File "/usr/local/lib/python3.10/site-packages/foca/__init__.py", line 3, in <module>
    from foca.foca import Foca  # noqa: F401
  File "/usr/local/lib/python3.10/site-packages/foca/foca.py", line 10, in <module>
    from foca.security.access_control.register_access_control import (
  File "/usr/local/lib/python3.10/site-packages/foca/security/access_control/register_access_control.py", line 15, in <module>
    from foca.models.config import (
  File "/usr/local/lib/python3.10/site-packages/foca/models/config.py", line 898, in <module>
    class CollectionConfig(FOCABaseConfig):
  File "/usr/local/lib/python3.10/site-packages/foca/models/config.py", line 923, in CollectionConfig
    client: Optional[pymongo.collection.Collection] = None
AttributeError: module 'pymongo' has no attribute 'collection'

This does not occur with PyMongo 4.7.0, where pymongo.collection exists.

It appears that somewhere along the line between 4.7 and 4.10, PyMongo removed the top-level collections module.

Quick workaround for apps using FOCA: Add pymongo==4.7 to your requirements.
