Use correct params for create component template

[danielmitterdorfer]

The Elasticsearch Python client does not accept a request body but rather requires parts of the body to be passed for the create component template API call. With this commit we adapt Rally to these changes.

Thanks for picking this up. LGTM.

Hmm, something's up with esrally install --quiet --http-port=19200 --node=rally-node --master-nodes=rally-node --car=4gheap,trial-license,x-pack-ml --seed-hosts="127.0.0.1:19300" --revision=current as part of rally-tracks-compat.

I can't repro this locally, so I suspect something is up with GH Actions since GitHub updated their SSH key on Friday. The blog post mentions:

GitHub Actions users may see failed workflow runs if they are using actions/checkout with the ssh-key option. We are updating the actions/checkout action in all our supported tags, including @v2, @V3, and @main. If you pin the action to a commit SHA and use the ssh-key option, you’ll need to update your workflow. You can read more about this process in our official documentation for Actions security hardening.

As far as I can tell, we don't use the ssh-key option, and my GH Actions-fu is non existent. @pquentin can you help here?

I see now that CI failing is related to this #1688

@pquentin agreed to take a look tomorrow.
