Add editoast --no-cache option

[flomonster]

This option allows to disable caching.
It's useful for developers working on core and using editoast endpoints.

Nice one. By the way, should this option be activated by default (simplifying the developer onboarding?). No cache means no Redis to deploy locally, so it might be interesting.

I don't want to enable it by default. Using docker compose we have a redis that runs easily. Disabling the cache makes the tile server very slow. Which is not good behavior, even for developers.
