feat: Add explicit schema bucket APIs

[stuartcarnie]

This PR introduces Cloud 2 specific APIs for managing explicit schema buckets. Most of the changes are in the cloud
source tree, as the feature is Cloud 2 only.

The Bucket type adds a schemaType property.

• For OSS it is expected to return implicit.
• For Cloud 2 it can be either implicit or explicit, once the feature is available.

@danxmoran / @glinton this is a Cloud 2 only feature at this point. It is possible we could move this to OSS at some later point. My question for you is

How would I extend the CLI tools to be able to support this Cloud 2.0 feature?

It would include

• modifying the bucket create command to allow specifying a schema-type of either implicit (default) or explicit
• modifying the bucket list command to show the schemaType property
• adding new commands to list, create and update existing measurement schemas for an explicit schema bucket

@stuartcarnie I'm pretty sure I wasn't the intended target? Boy, at least I hope so. :)

Oi! Sorry Dan, I meant to tag @danxmoran

@stuartcarnie I'd first merge your changes in this branch with the changes in #36, so you're up-to-date with the tweaks needed to make codegen work. After that, I'd add any of the paths+schemas you want the CLI to use into src/cli.yml.

Once you've committed the above, you can:

1. Update the codegen script in influx-cli to point at it. In the short-term you'll want to work off of the dm-port-bucket-7 branch, but I'm hoping to merge it to main soon.
2. Run make openapi to regenerate the client-side code using the new API docs
3. Modify the existing bucket commands to take the new parameter
4. Add new commands

You'll be the first not-me contributor in the new repo, so please let me know any feedback you have on the codegen flow / process of adding a new command in the new CLI codebase.

Great info, thanks @danxmoran! I'll work through that today

[danxmoran]

I made influxdata/influx-cli#51 to track the work over there

[stuartcarnie]

Are you going to merge #36 today, so I can work of master or should I rebase on that branch?

[danxmoran]

Just merged it, you should be set to work off of master
