* chore: merge authorization contexts
Instead of 2 auth contexts from apikey and dbauthz, merge them to
just use dbauthz. It is annoying to have two.
* fixup authorization reference
* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
feat: Add initial AuthzQuerier implementation
- Adds package database/dbauthz that adds a database.Store implementation where each method goes through AuthZ checks
- Implements all database.Store methods on AuthzQuerier
- Updates and fixes unit tests where required
- Updates coderd initialization to use AuthzQuerier if codersdk.ExperimentAuthzQuerier is enabled
* chore: Implement standard rbac.Subject to be reused everywhere
An rbac subject is created in multiple spots because of the way we
expand roles, scopes, etc. This difference in use creates a list
of arguments which is unwieldy.
Use of the expander interface lets us conform to a single subject
in every case
* feat: Member roles are implied and never exlpicitly added
* Rename "GetAllUserRoles" to "GetAuthorizationRoles"
* feat: Add migration to remove implied roles
* rename user auth role middleware
Abstracting coderd into an interface added misdirection because
the interface was never intended to be fulfilled outside of a single
implementation.
This lifts the abstraction, and attaches all handlers to a root struct
named `*coderd.API`.
