Description

Currently, not supplying a value to a node template operation input that is defined with `required: false` in its type passes the service creation stage, but when trying to execute a workflow on the service, the execution refuses to start, claiming that this input is missing.

Example:

# (assuming a 'create.sh' script is present)

tosca_definitions_version: tosca_simple_yaml_1_0

node_types:
  nodes.Container.Application.Kubernetes:
    derived_from: tosca.nodes.Root
    interfaces:
      Standard:
        create:
          inputs:
            labels:
              type: string
              required: false
          implementation: create.sh

topology_template:
  node_templates:
    web_app:
      type: nodes.Container.Application.Kubernetes

Running the install workflow will alert that we didn't give a value to the `labels` input, and won't start
