* fix: Improve `coder server` shutdown procedure
This commit improves the `coder server` shutdown procedure so that all
triggers for shutdown do so in a graceful way without skipping any
steps.
We also improve cancellation and shutdown of services by ensuring
resources are cleaned up at the end.
Notable changes:
- We wrap `cmd.Context()` to allow us to control cancellation better
- We attempt graceful shutdown of the http server (`server.Shutdown`)
because it's less abrupt (compared to `shutdownConns`)
- All exit paths share the same shutdown procedure (except for early
exit)
- `provisionerd`s are now shutdown concurrently instead of one at a
time, the also now get a new context for shutdown because
`cmd.Context()` may be cancelled
- Resources created by `newProvisionerDaemon` are cleaned up
- Lifecycle `Executor` exits its goroutine on context cancellation
Fixes#3245
This brings an async service that parses and
provisions to life! It's separated from coderd
intentionally to allow for simpler testing.
Integration with coderd will come in another PR!
* feat: Create provisioner abstraction
Creates a provisioner abstraction that takes prior art from the Terraform plugin system. It's safe to assume this code will change a lot when it becomes integrated with provisionerd.
Closes#10.
