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.
Customer feedback indicated projects was a confusing name.
After querying the team internally, it seemed unanimous
that it is indeed a confusing name.
Here's for a lil less confusion @ashmeer7 🥂
* feat: Add AWS instance identity authentication
This allows zero-trust authentication for all AWS instances.
Prior to this, AWS instances could be used by passing `CODER_TOKEN`
as an environment variable to the startup script. AWS explicitly
states that secrets should not be passed in startup scripts because
it's user-readable.
* Fix sha256 verbosity
* Fix HTTP client being exposed on auth
This update exposes the workspace name and owner, and changes
authentication methods to be explicit. Implicit authentication
added unnecessary complexity and introduced inconsistency.
