* 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 the webpage for accessing a web terminal
* Add terminal page tests
* Use Ticker instead of Timer
* Active Windows mode on Windows
This makes setting up git a bit simpler, and users
can always override these values!
We'll probably add a way to disable our Git integration
anyways, so these could be part of that.
These values were ignored. Environment variables are applied to
new sessions, and are refreshed on reconnect. This is cool because
a workspace could be updated with new environment variables without
requiring a complete start/stop.
The startup script is only ran once regardless of changes, which
feels like the expected behavior.
This enables a "kubernetes_pod" to attach multiple agents that
could be for multiple services. Each agent is required to have
a unique name, so SSH syntax is:
`coder ssh <workspace>.<agent>`
A resource can have zero agents too, they aren't required.
