GraphServer Resource and Remote Workflow Node

[rsamf]

A GraphServer resource can be connected as a resource to a Remote Workflow node which is a special Group node that forwards the internal subflow to the specified graphserver. The GraphServer Resource is simply just a host address and port. Additionally, a Group node can be converted into a Remote Workflow, through its context menu. IaC through Terraform will require significant customization and will be left for further investigation (i.e. figuring out how users will want).
