This change allows the agent to handle common shutdown signals like
interrupt, hangup and terminate and initiate a graceful shutdown.
As long as terraform providers initiate graceful shutdowns via the
aforementioned signals, things like SSH connections will be closed
immediately on shutdown instead of being left hanging/timing out due to
the agent being abruptly killed.
Refs: #4677, #5901
* chore: rename `AgentConn` to `WorkspaceAgentConn`
The codersdk was becoming bloated with consts for the workspace
agent that made no sense to a reader. `Tailnet*` is an example
of these consts.
* chore: remove `Get` prefix from *Client functions
* chore: remove `BypassRatelimits` option in `codersdk.Client`
It feels wrong to have this as a direct option because it's so infrequently
needed by API callers. It's better to directly modify headers in the two
places that we actually use it.
* Merge `appearance.go` and `buildinfo.go` into `deployment.go`
* Merge `experiments.go` and `features.go` into `deployment.go`
* Fix `make gen` referencing old type names
* Merge `error.go` into `client.go`
`codersdk.Response` lived in `error.go`, which is wrong.
* chore: refactor workspace agent functions into agentsdk
It was odd conflating the codersdk that clients should use
with functions that only the agent should use. This separates
them into two SDKs that are closely coupled, but separate.
* Merge `insights.go` into `deployment.go`
* Merge `organizationmember.go` into `organizations.go`
* Merge `quota.go` into `workspaces.go`
* Rename `sse.go` to `serversentevents.go`
* Rename `codersdk.WorkspaceAppHostResponse` to `codersdk.AppHostResponse`
* Format `.vscode/settings.json`
* Fix outdated naming in `api.ts`
* Fix app host response
* Fix unsupported type
* Fix imported type
This feature is used by the coder agent to exchange a new token. By
protecting the SessionToken via mutex we ensure there are no data races
when accessing it.
* fix: Refactor agent to consume API client
This simplifies a lot of code by creating an interface for
the codersdk client into the agent. It also moves agent
authentication code so instance identity will work between
restarts.
Fixes#3485 and #4082.
* Fix client reconnections
It's possible that an agent starts before a build is reported
as complete. This ensures the version is successfully sent
before the startup completes.
Fixes#4151.
* fix: Add coder user to docker group on installation
This makes for a simpler setup, and reduces the likelihood
a user runs into a strange issue.

* fix: Add reaper to coder agent
- The coder agent runs as PID 1 in some of our Docker workspaces.
In such cases it is the responsibility of the init process to
reap dead processes. Failing to do so can result in an inability
to create new processes by running out of PIDs.
This PR adds a reaper to our agent that is only spawned if it
detects that it is PID1.
* fix: Update GIT_COMMITTER_NAME to use username
This was a mistake when adding the committer fields 🤦.
* fix: Use environment variables for agent authentication
Using files led to situations where running "coder server --dev" would
break `gitssh`. This is applicable in a production environment too. Users
should be able to log into another Coder deployment from their workspace.
Users can still set "CODER_URL" if they'd like with agent env vars!
* feat: Add web terminal with reconnecting TTYs
This adds a web terminal that can reconnect to resume sessions!
No more disconnects, and no more bad bufferring!
* Add xstate service

* Add terminal page tests
* Use Ticker instead of Timer
* Active Windows mode on Windows
