editoast: update temporary speed limit groups import endpoint

[Sh099078]

fixes https://github.com/OpenRailAssociation/osrd/issues/9399

• [x] Add an endpoint /infra/{infra_id}/delimited_area that returns the list of track sections inside an area delimited by entry and exit directed locations (i.e. a position on a track and a direction, similar to a light version of a sign with only the relevant positional information).
• [x] Stop the graph exploration at a specified distance from the entries if an end position is missing. It is considered that and end position is missing if none has been found after exploring the track sections on a specified maximum distance from the entries without having found any exit.
• [x] Refactorize temporary_speed_limit.rs tests.

I've just seen the issue. I don't really like the idea of having several endpoints to create the same object.

wdym? there is only /temporary_speed_limit_group

I'd really prefer this to be done on the import side and not in editoast. When importing, do you have information on the "line" "track" and "pk" of the start and end of the temporary speed limit zone?

We have signals and their location, so we could get that, yes. The import side does not have the full track graph with the various corrections (eg. we do not run the kd-tree), and can't run them easily since it lacks track geometry.

I mean that we should keep the CRUD endpoints of an object quite simple and close from it's model. Usualy transformation are done by the user (using utility endpoint or by it's own). Example: Train schedule / Workschedule / Infra / RS...

Since we don't have LRS in OSRD (for now) it's really difficult to import linear objects such as speed limits (all of them). However, all these objects are converted from a start point to an end point into a list of track ranges in the import script and not by editoast. This PR goes against this paradigm, hence my caution.

Maybe editoast can help with this, but with a more generic and reusable endpoint :shrug:

[Sh099078]

Following discussions with @Khoyo and @flomonster the temporary speed limits group endpoint has been split into two:

• A temporary speed limit groups creation endpoint (unchanged, accepts an LTV with a list of track sections).
• A /infra/{infra_id}/delimited_area endpoint that returns the list of track sections inside an area delimited by a list of entries and exits (positions on a track with a direction).
