✨ Load node properties on demand (#1089)

* ⚡ Changed rest api endpoint to omit node properties by default.
⚡ Created another endpoint to return all node information based on a list of names

* refactor: changed endpoint to POST instead of GET

* Changed properties to be optional for node description

* Removed eager loading for node properties.

All nodes will have their properties fetched when used in a workflow.
Works when opening an already saved workflow, creating a new one from
scratch or pasting JSON / URLs.

* Removing unnecessary dependency
