Just moved `rbac.Action` -> `policy.Action`. This is for the stacked PR to not have circular dependencies when doing autogen. Without this, the autogen can produce broken golang code, which prevents the autogen from compiling.
So just avoiding circular dependencies. Doing this in it's own PR to reduce LoC diffs in the primary PR, since this has 0 functional changes.
Currently, importing `codersdk` just to interact with the API requires
importing tailscale, which causes builds to fail unless manually using
our fork.
Moves healthcheck report-related structs from coderd/healthcheck to codersdk
This prevents an import cycle when adding a codersdk.Client method to hit /api/v2/debug/health.
Adds some debug endpoints for looking into the DERP server.
The `api/v2/debug/derp/traffic` endpoint requires the `ss` utility to be present in order to function. I have *not* added the `iproute2` package to our base image as it adds 11MB, so this endpoint won't be useful by default. However, in a debugging situation, we could exec into the container and then `apk add iproute2`, or build a special debug image.
The `api/v2/debug/expvar` handler contains DERP metrics as well as commandline and memstats.

If we find the DERP metrics useful we could consider how to include them in Prometheus scrapes based on the tailnet `varz` package. That's for a later PR if at all.
* 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
