feat(core): providers can now reference each others' outputs

Architecturally this involves combining provider resolution,
status checks and environment prep into one flow. That won't impact
most commonly used CLI commands (deploy, test, dev), but other commands
that need to use provider configuration will take longer to start.

The negative impact will of course be mitigated when we're running
Garden as a persistent daemon. The benefit is that we can now write
providers that provide information to other providers, e.g. Terraform
or Cloudformation providers that feed connection information to
Kubernetes providers etc.
