Automatically upload precomputed blocks to object storage

[trevorbernard]

Run a Mina node and log the precomputed blocks into a bucket we control. E.g. S3 Bucket

Just need to resolve merge conflicts MinaProtocol/mina#13236. However, this solution will only allow us to get blocks in the transition frontier. Hosting a bucket of all precomputed blocks is another story altogether.

@Isaac-DeFrain My interpretation of this issue is that it is about the hosting of a precomputed blocks bucket. I'll take it.

https://granola-mina-blocks.se-sto-1.linodeobjects.com is now where we host our (corrected) block files. Also, we do not use gsutil to download blocks in our regression suite.

A final step is to create a Mina node that uploads blocks to the bucket in an automated fashion.

https://blocks.minasearch.com now points to our object storage. You cannot list the files (using your browser), but if you know a block heigh and state hash, you can download the file (using stand HTTP).

Example: https://blocks.minasearch.com/mainnet-417740-3NLJ6bJH4QQhjqegTiZbo138V1TX1KxBrNhqAMzMDrnGoaN6QPVW.json

P.S. rclone still has the ability to list/locate all the files in the bucket.
