feat: Add bucket schema management commands

[stuartcarnie]

This PR extends the tool with commands to manage explicit schema buckets per #51.

Changes include:

• Modified the bucket create command to allow specifying a schema-type of either implicit (default) or explicit
• Modified the bucket list command to show the schemaType property as a new column, Schema Type
• Added a new bucket-schema command, with the following sub-commands:
  • create to create a new measurement schema for an existing explicit schema bucket;
  • update to add new columns to an existing measurement schema; and
  • list to find and print information about existing measurement schemas.

Would it make sense to move our existing global flag vars out of main.go and into this file?

[stuartcarnie]

I think you could move the variables to this package and leave the bindings in main – that keeps with your mantra of leaving urfave logic in cmd

NOTE: I've modified the script to reference the updated spec via https://github.com/influxdata/openapi/tree/sgc/issues/9672 to validate this PR via CI. I've opened influxdata/openapi#34 for review and will remove the last commit when it merges to main

This can rebase against main

Not sure what happened, but however sgc/experimental was merged to main caused the branches to diverge, so I had to cherry pick all the individual commits. 🤷🏻

Hi @danxmoran – let me know if there are still any outstanding questions you have. I've added a number of unit tests for all the bucket-schema commands.

Thanks for the contribution @stuartcarnie! Exciting to see a cloud-focused feature land early.
