[CX-CLEANUP] - DA Integrated Storage

[jparr721]

Closes #2621

We want to integrate a persistent storage interface within HotShot to enable the application to manage data storage effectively. This feature aims to address potential data storage issues (e.g., full disk space) that can prevent nodes from storing DA blobs or VID shares.

This PR:

1. Creates Storage Trait
2. Initializes Storage in SystemTask's init
3. Add Storage Operations on DA Proposals
   • If this fails, do not vote on the proposal and exit the event handler.
4. Add Storage Operations on DA Proposals VID Shares
   • If this fails, do not vote on the VID disperse, otherwise, use the old logic to vote.
5. Refactor In-memory Payload/VID Stores: (Tracking [CX_CLEANUP] - Remove BlockPayload from Leaf and associated types. #2808)

This code also implements a number of changes to introduce a TestBlockStorage type for use in the various testing components.

Key places to review:

All of the tests and test interface changes. I had to update the view_generator to support the various DA related things that we wanted to add.

Changes look good to me, but lets give @jbearer some time to answer your question

Open to thoughts here. See the tests below for examples. I just need a cheesy "fail immediately" system that does not change the interface. The idea here is that I just want to make sure that any logical changes can catch a regression in the failure case for an append.

Yeah this is fine, it's just a dummy type for our tests anyway

This is copied direct from the test as it was just to maintain parity. I've been trying to modernize tests as I touch them.
