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.
The agentsdk currently does a remap of the DERP map to change the
EmbeddedRelay node's URL to match the agent's access URL.
This PR makes changes to the `workspacesdk` (used by clients like the
CLI) and `vpn` (used by Coder Desktop) to match this behavior.
This enables us the ability to try Coder clients in dogfood over a VPN
without changing the global access URL.
Closes#17982.
The purpose of this PR is to expose network latency via the API used by Coder Desktop.
This PR has the tunnel ping all known agents every 5 seconds, in order to produce an instance of:
```proto
message LastPing {
// latency is the RTT of the ping to the agent.
google.protobuf.Duration latency = 1;
// did_p2p indicates whether the ping was sent P2P, or over DERP.
bool did_p2p = 2;
// preferred_derp is the human readable name of the preferred DERP region,
// or the region used for the last ping, if it was sent over DERP.
string preferred_derp = 3;
// preferred_derp_latency is the last known latency to the preferred DERP
// region. Unset if the region does not appear in the DERP map.
optional google.protobuf.Duration preferred_derp_latency = 4;
}
```
The contents of this message are stored and included on all subsequent upsertions of the agent.
Note that we upsert existing agents every 5 seconds to update the `last_handshake` value.
On the desktop apps, this message will be used to produce a tooltip similar to that of the VS Code extension:

(wording not final)
Unlike the VS Code extension, we omit:
- The Latency of *all* available DERP regions. It seems not ideal to send a copy of this entire map for every online agent, and it certainly doesn't make sense for it to be on the `Agent` or `LastPing` message.
If we do want to expose this info on Coder Desktop, we should consider how best to do so; maybe we want to include it on a more generic `Netcheck` message.
- The current throughput (Bytes up/down). This is out of scope of the linked issue, and is non-trivial to implement. I'm also not sure of the value given the frequency we're doing these status updates (every 5 seconds).
If we want to expose it, it'll be in a separate PR.

Previously we were configuring using the display name of the user, which
may contain spaces, special characters, and isn't unique. This was
always supposed to be the username.
Migrates us to `coder/websocket` v1.8.12 rather than `nhooyr/websocket` on an older version.
Works around https://github.com/coder/websocket/issues/504 by adding an explicit test for `xerrors.Is(err, io.EOF)` where we were previously getting `io.EOF` from the netConn.
Closes#14734.
- Each outgoing agent upsertion also includes the timestamp of the last wireguard handshake.
- Agent upsertions will be created, for existing agents, with an updated last handshake time on a regular, fixed, interval of 10 seconds.
Addresses #14734.
This PR wires up `tunnel.go` to a `tailnet.Conn` via the new `/tailnet` endpoint, with all the necessary controllers such that a VPN connection can be started, stopped and inspected via the CoderVPN protocol.
