Subject: [PATCH] feat: Add app support

This adds what are presently named "devurls" in v1.
It seems this is a dated term, since this allows
much more than accessing applications via URL.

"coder open <name>" will launch any apps defined.
If in the web, it'll open either a web terminal or
port forward to the desired application. If in the terminal,
it'll open the browser, or launch the command over SSH.

+## Schema
+
+### Required
+
+- `agent_id` (String) The "id" property of a "coder_agent" resource to associate with.
+
+### Optional
+
+- `command` (String) A command to run in a terminal opening this app. In the web, this will open in a new tab. In the CLI, this will SSH and execute the command.
+- `icon` (String) A URL to an icon that will display in the dashboard. View built-in icons here: https://github.com/coder/coder/tree/main/site/static/icons. Use a built-in icon with `data.coder_workspace.me.access_url + "/icons/<path>"`.
+- `id` (String) The ID of this resource.
+- `name` (String) A display name to identify the app.
+- `target` (String) A URL to be proxied to from inside the workspace.
