New Container: CrateDB

[surister]

What is the new container you'd like to have?
Container for CrateDB database.

Why not just use a generic container for this?

CrateDB has it's own wait strategy as well as the need to have different setups, for example to form a cluster we'd need 3 docker instances. These would be better implemented here, upstream.

We have already a working implementation thanks to @amotl https://github.com/crate/cratedb-toolkit/blob/main/cratedb_toolkit/testing/testcontainers/cratedb.py

Btw, I will submit a PR for this soon, I'd only need some kind of review from the maintainers, thanks in advance!

One note please, as DbContainer is been deprecated you should not use it as a baseline for any new additions.
(As discussed on #884)

depending on what you want to implement and how important it is to share to get people started with cratedb, its a good chance we will merge it.

These would be better implemented here, upstream.

in general we aim for the examples in this repo to be a starting point, not a final destination. so we encourage you to continue maintenance if you have the means. e.g. i do not maintain the community modules (we get PRs and i merge them but its not my focus, i have barely enough bandwidth for core)
