This removes split ownership for workspaces. They are now
a resource of organizations and have a designated owner,
which is a user.
This enables simple administration for commands like:
- `coder stop ben/dev`
- `coder build logs colin/arch`
or if we decide to allow administrators to access workspaces,
they could even SSH using this syntax: `coder ssh colin/dev`.
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.
