fix: add names to redis and mongo volumes

[mohd-akram]

The mongo and redis images provide additional volumes that aren't specified in the compose files. This ensures they have proper names and aren't anonymous.

Thanks for this PR @mohd-akram! Aside from needing a rebase, are the changes ready for review?

[mohd-akram]

@itsjeyd Yup, they are.

[itsjeyd]

Thanks @mohd-akram, I'm lining this up for a test run now. Once the build is green the changes can go to engineering review.

LGTM

I'm unable to rebase this, but it's good as far as I'm concerned.

Out of curiosity, is there some symptom that this fixes, or is this just to make sure that our docker-compose lists all of the relevant volumes? (Happy to merge either way, once the branch is brought up to date.)

[mohd-akram]

Yes. Every time you do docker-compose down followed by docker-compose up, it will create a new anonymous volume. Doing this a few times causes the volume list to be littered with nameless volumes providing no clue on what they contain. Providing a name makes docker-compose re-use the same volume while making it clear what the volume contains. I've rebased the branch.

[timmc-edx]

Ah! I'd wondered what all those anonymous volumes were from when I ran docker volume ls. :-)
