Add FLAME support 🔥

[chrismccord]

Note this will require a FLAME release phoenixframework/flame#40

Example notebook deployed on fly.io with working branch:

flame_git_ref = "cm-code-paths"
System.put_env("FLAME_GIT_REF", flame_git_ref)
Mix.install([:kino, {:flame, github: "phoenixframework/flame", ref: flame_git_ref}])

Kino.start_child!(
  {FLAME.Pool,
    name: :flame_test,
    code_sync: [
      verbose: true,
      copy_paths: true,
      sync_paths: [Path.join(System.tmp_dir!(), "livebook_runtime")]
    ],
    min: 1,
    max: 1,
    max_concurrency: 10,
    backend: {FLAME.FlyBackend, 
      cpu_kind: "performance", cpus: 4, memory_mb: 8192, 
      token: System.fetch_env!("FLY_API_TOKEN"),
      env: Map.take(System.get_env(), ["LIVEBOOK_COOKIE", "FLAME_GIT_REF"]),
    },
    idle_shutdown_after: :timer.minutes(5),
    log: :info}
)


defmodule Foo do
  def test(args), do: "works #{inspect(args)} #{node()}"
end

FLAME.call(:flame_test, fn ->
  Foo.test(1234)
end)
