What were you trying to do that didn't work?

When using SQLite (this may affect other DB as well), the number of connections to the database grows indefinitely, reaching the maximum number of connections. This is described upstream in https://github.com/keylime/keylime/issues/1689

Apparently the connections to the database are not closed properly, leading to a connection leak.

This happened multiple times in CI execution and an example can be seen here:

What is the impact of this issue to you?

When the number of open connections to the database reach the configured limit, it does not accept new connections, blocking the access to the database

Please provide the package NVR for which the bug is seen:

keylime-7.12.1-6.el10

How reproducible is this bug?:

Happens often in CI

Steps to reproduce

1. Run the CI tests. It happens usually during the execution of the 

Expected results

The connections to the DB are properly closed and there is no accumulation of open connections

Actual results

The connections to the DB accumulates until the maximum number of connections is reached
