Fixes all our Go file imports to match the preferred spec that we've _mostly_ been using. For example:
```
import (
"context"
"time"
"github.com/prometheus/client_golang/prometheus"
"golang.org/x/xerrors"
"gopkg.in/natefinch/lumberjack.v2"
"cdr.dev/slog/v3"
"github.com/coder/coder/v2/codersdk/agentsdk"
"github.com/coder/serpent"
)
```
3 groups: standard library, 3rd partly libs, Coder libs.
This PR makes the change across the codebase. The PR in the stack above modifies our formatting to maintain this state of affairs, and is a separate PR so it's possible to review that one in detail.
Upgrades to slog v3 which includes a small, but backward incompatible API change to the acceptible call arguments when logging. This change allows us to verify via compile time type checking that arguments are correct and won't cause a panic, as was possible in slog v1, which this replaces (v2 was tagged but never used in coder/coder).
It also updates dependencies that also use slog and were updated.
I've left the `aibridge` dependency as a commit SHA, under the assumption that the team there (cc @pawbana @dannykopping ) will tag and update the dependency soon and on their own schedule.
Other dependencies, I pushed new tags.
This should resolve https://github.com/coder/internal/issues/728 by
refactoring the ResourceMonitorAPI struct to only require querying the
resource monitor once for memory and once for volumes, then using the
stored monitors on the API struct from that point on. This should
eliminate the vast majority of calls to `GetWorkspaceByAgentID` and
`FetchVolumesResourceMonitorsUpdatedAfter`/`FetchMemoryResourceMonitorsUpdatedAfter`
(millions of calls per week).
Tests passed, and I ran an instance of coder via a workspace with a
template that added resource monitoring every 10s. Note that this is the
default docker container, so there are other sources of
`GetWorkspaceByAgentID` db queries. Note that this workspace was running
for ~15 minutes at the time I gathered this data.
Over 30s for the `ResourceMonitor` calls:
```
coder@callum-coder-2:~/coder$ curl localhost:19090/metrics | grep ResourceMonitor | grep count

```
And over 1m for the `GetWorkspaceAgentByID` calls, the majority are from
the workspace metadata stats updates:
```
coder@callum-coder-2:~/coder$ curl localhost:19090/metrics | grep GetWorkspaceByAgentID | grep count

As part of the new resources monitoring logic - more specifically for
OOM & OOD Notifications , we need to update the AgentAPI , and the
agents logic.
This PR aims to do it, and more specifically :
We are updating the AgentAPI & TailnetAPI to version 24 to add two new
methods in the AgentAPI :
- One method to fetch the resources monitoring configuration
- One method to push the datapoints for the resources monitoring.
Also, this PR adds a new logic on the agent side, with a routine running
and ticking - fetching the resources usage each time , but also storing
it in a FIFO like queue.
Finally, this PR fixes a problem we had with RBAC logic on the resources
monitoring model, applying the same logic than we have for similar
entities.
