Add Delete geoip database configuration API

[pquentin]

Part of #2810, like #2815 and #2823. There's an output conflict with #2823 that I will fix when one of the two will have been merged.

You can validate these APIs yourself by using the make validate target.

The backport to 8.15 failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-8.15 8.15
# Navigate to the new working tree
cd .worktrees/backport-8.15
# Create a new branch
git switch --create backport-2824-to-8.15
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 21ef23261b8bcfd6fbb544ab5df8484b3e86e039
# Push it to GitHub
git push --set-upstream origin backport-2824-to-8.15
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-8.15

Then, create a pull request where the base branch is 8.15 and the compare/head branch is backport-2824-to-8.15.

@pquentin Is this really an optional parameter? This triggered a validation rule in my code generator.

The rule requires a mandatory parameter to be used in all available urls for an endpoint and an optional parameter to not be used in all available urls for an endpoint.

[flobernd]

We currently have only one url for this endpoint:

"urls": [
        {
          "methods": [
            "DELETE"
          ],
          "path": "/_ingest/geoip/database/{id}"
        }
]

In other words: If that endpoint does not support an additional url like "/_ingest/geoip/database" (without the {id}), we should make the path parameter mandatory.

Sorry! #2837 fixes it.
