Bug Report

Description

Datajoint connection cannot be defined with the python with, and using with is the regular way to make sure a connection is closed after dj.conn().

Reproducibility

Include:

• OS (Linux)
• Python Version 3.9
• MySQL Version 8.0
• MySQL Deployment Strategy (remote)
• DataJoint Version 0.14.0
• Minimum number of steps to reliably reproduce the issue

with dj.conn(**conn_info) as connection:
            print(connection)

• Complete error stack as a result of evaluating the above steps

Traceback (most recent call last):
  File , in <module>
    app.lambda_handler(payload.EVENT, payload.CONTEXT)
  File , line 136, in lambda_handler
    with dj.conn(**conn_info):
AttributeError: __enter__

Expected Behavior

Using with to create a datajoint db connection, and close the connection at the end of the with clause.

AFAIK, dj.Connection does not implement a context manager. So this issue is a feature request to add context manager functionality to dj.Connection, not a bug fix.
