Extracts part of the prometheus middleware that stores the route
information in the request context into its own middleware. Also adds
request method information to context.
Relates to https://github.com/coder/internal/issues/1214
I noticed while looking at scale test metrics that we don't always
report a useful path in the API request metrics.
There are a lot of requests with path `/*`. I chased this problem to the
workspace proxy, where we mount a the proxy router as a child of a
"root" router to support some high level endpoints like `latency-check`.
Because we query the path from the Chi route context in the prometheus
middleware _before_ the request is actually handled, we can have a
partially resolved pattern match only corresponding to the root router.
The fix is to always re-resolve the path, rather than accept a partially
resolved path.
* 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
This allows deployments using our Prometheus export t determine
the number of active users in the past hour.
The interval is an hour to align with API key last used refresh times.
SSH connections poll to check shutdown time, so this will be accurate
even on long-running connections without dashboard requests.
