Testing the new async client

[jbusecke]

I actually f'ed up before and pushed to main. I cancelled the action and am just adding this PR so I can convince myself that things run smoothly in the end-to-end scenario.

Overall the new async client seems to work well and fast! We are now searching/combining results from multiple index nodes. Check across data nodes and dataset metadata that we have all files (to avoid #53 in the future), and we have all the metadata in the world to retest datasets afterwards ( #154).

As far as I am concerned, if we cannot fix an issue with the entire API response and the data, it is out of our responsibility.

Those changes will address the following issues:

• Part ways toward Reintegrate tracking ID #133
• Closes Can we track some of the pangeo-forge-esgf parameters into the written store? #32 (see also Reintegrate tracking ID #133 (comment))
• Closes out Add provenance metadata (urls, timestamp) to zarr store #11 (even though that was mostly addressed by adding the AttributeInjection Stage earlier)
