✨ Enhancement/allow node port to get set value

[sanderegg]

What do these changes do?

to bring the dask sidecar in:

• the node ports package now allow to get/set the link to S3-backed file without actually directly downloading/uploading the file through the node_ports, but in a delayed manner (the dask-sidecar has no access to the database, but still need a pre-signed link to download/upload)

some additional small fixes/refactors

So, this PR introduces:

• simcore-sdk's port.get_value resolves port and file links into valid downloadable links and port.get resolves to a value in memory or in a file-path. Some thoughts:
  • Naming of all these functions (i.e. get_value or get) are too generic and cannot what it does without analyzing the code
  • Same with Item and ContreteItem. Why a path is a concrete item? It is rather a link to the concrete. I find there are too many indirections (links to links to links) and are not clearly organized.
• director service waits for registry to be responsive upon startup.
  • consider on_startup for setup
