blob-dir is not enabled by default

BUG

What I did:

• I installed & configured plone 6 installation following the official documentation at Plone 6: The Install
  • this gave me 1 instance with direct db.
• I wanted to scale up with multiple instances using ZEO server, so I followed Ex: Plone Multi Clients using ZEO

What I expect to happen:

• ✓ Multi clients/instances sharing ZEO database on localhost:8100.
• ✓ Ability to connect to ZEO database from multiple clients.
• ✓ Ability to add/edit/remove from any client.
• ✕ Ability to upload files from any client.

  What actually happened:

• Was not able to upload files and getting this error: https://github.com/plone/Products.CMFPlone/issues/3345#issue-1037650436
• Clients are able to connect to ZEO server and add/edit data but not blob

  How it was solved:

• Using cookiecutter-zope-instance, directing the blob location for the instance to the ZEO blob file:
  • Ex: db_blobs_location: /path/to/zeo/var/blobs:
  • This will generate the following zope.config
• Now, to create a ZEO server, I used mkzeoinstance zeo localhost:8100
  • This will generate /zeo/etc/zeo.conf - Edit fix on line 17
  • Doing so fix the file upload problem.

What version of Python and Zope/Addons I am using: Python 3.9 - leatest.

Adding a configuration option to pass in the path to the blob directory would be appreciated. A pull request is welcome.
