We currently call GetWorkspaceAgentByID millions of times at scale
unnecessarily. This PR embeds immutable fields into the relevant
services instead of fetching for them every time.
resolves https://github.com/coder/scaletest/issues/84
Confirmed with a 10k scaletest that this changeset takes the query from
10M+ queries down to 39k
Parent agents were re-using AuthInstanceID when spawning child agents.
This caused GetWorkspaceAgentByInstanceID to return the most recently
created sub agent instead of the parent when the parent tried to refetch
its own manifest.
Fix by not reusing AuthInstanceID for sub agents, and updating
GetWorkspaceAgentByInstanceID to filter them out entirely.
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"
)
```

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.
The incorrect assumption that slugs were unique per-agent was made when
the subagent API was implemented. Whilst this PR doesn't completely
enforce that, we instead compute a stable hash to prefix the slug that
should provide a reasonable level of probability that the slug will be
unique.
Completely missed this in the original PR for adding support for
creating sub agents. This now allows specifying a list of display apps
to be added to the agent.
Closes https://github.com/coder/internal/issues/619
Implement the `coderd` side of the AgentAPI for the upcoming
dev-container agents work.
`agent/agenttest/client.go` is left unimplemented for a future PR
working to implement the agent side of this feature.
