cloudhead 1d167581f2 cob: Introduce xyz.radicle.id COB
Introduces a new COB type to store repository identity documents.

The reason for this change is to:

1. Simplify the code, as the identity document logic resembled a COB,
   yet it had custom logic. This allows existing COB code to be used for
   identities.
2. Make identity document update logic more flexible, since COB actions
   can be added in the future.
3. Re-purpose existing tools around COBs to work on identities, eg. `rad
   cob`.
4. Unify the concept of an identity change proposal, with regular identity
   changes. This means we can remove the `id.proposal` COB in favor of
   using the `id` COB itself.

Notes
-----

* Each repository has one Identity COB.
* The `Proposal` COB has been repurposed into the `Identity` COB.
* Identity documents are stored as *embeds* inside the Identity COB
  actions.
* The action that contains new document versions is called `revision`,
  just like the Patches COB.
* The namespaced `rad/id` ref is a symbolic reference to that Identity
  COB.
* The canonical `rad/id` ref is a direct reference to the commit in the
  Identity COB that contains the latest *accepted* revision of the
  document.
* All commands for managing identities have been folded into `rad id`.
  Hence `rad delegate` and `rad edit` are removed.
* The concept of "rebasing" an identity document is gone.
* The `rad id` output has been updated to match the style of other
  commands.
* When a revision has enough signatures, it is automatically adopted as
  the current identity, there is no longer the need for a "commit"
  action.
* When an identity revision is proposed, and the current identity has a
  threshold of `1`, that identity is automatically accepted due to the
  above point.
* The idea of "verifying a peer's identity branch" no longer applies, as
  COBs cannot be verified one history at a time.
* Since the root commit of the Identity COB does not have a "Resource"
  to point to (it would have to point to itself, which is impossible),
  we've made the resource id optional for COBs.

If we have fetched a project, then we do not have a fork of the repository in the storage, i.e. there is no ref hierarchy for our NID. This is demonstrated below where our NID is z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk:

$ rad inspect rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --refs
z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi
└── refs
    ├── cobs
    │   └── xyz.radicle.id
    │       └── [...]
    ├── heads
    │   └── master
    └── rad
        ├── id
        └── sigrefs

To remedy this, we can use the rad fork command for the project we wish to fork:

$ rad fork rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji
✓ Forked project rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji for z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk

Now, if we rad inspect the project's refs again we will see that we have a copy of the main set of refs:

$ rad inspect rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --refs
z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi
└── refs
    ├── cobs
    │   └── xyz.radicle.id
    │       └── [...]
    ├── heads
    │   └── master
    └── rad
        ├── id
        └── sigrefs
z6Mkt67GdsW7715MEfRuP4pSZxJRJh6kj6Y48WRqVv4N1tRk
└── refs
    ├── heads
    │   └── master
    └── rad
        └── sigrefs

We are now able to setup a remote in our own working copy of the project and push to our own fork.
