<!-- Provide a general summary of your changes in the Title above -->

### Motivation and context
<!-- Why is this change required? What problem does it solve? If it
fixes an open
issue, please link to the issue here. Describe your changes in detail,
add
screenshots. -->
These types of data have different characteristics and we have different
expectations on them:

* job queues are small and we'd rather not lose them (although losing
them is not fatal);

* cached chunks are large and we don't care if we lose them.

We currently store both in KeyDB, which has shown itself to not be
especially reliable. A few times we've had to clear the KeyDB store due
to data corruption, which destroyed the queues as well. While we'll
probably end up replacing KeyDB with something else, it would still be
useful to have the ability to just clear the cache volume without taking
out the job queues in the process.

As a solution to this, add a Redis service to be used only for the
queues (and potentially for other small data items). Using the original
Redis instead of KeyDB should also help with reliability (at least as
far as the job queues are concerned).

### How has this been tested?
<!-- Please describe in detail how you tested your changes.
Include details of your testing environment, and the tests you ran to
see how your change affects other areas of the code, etc. -->
I checked the CVAT can still start using the development environment
instructions, the Compose file and the Helm chart.
