class_docstr: An execution parameter in a ComponentSpec.
  
  This type of parameter should be specified in the PARAMETERS dict of a
  ComponentSpec:
  
  class MyCustomComponentSpec(ComponentSpec):
    # ...
    PARAMETERS = {
        'internal_option': ExecutionParameter(type=str),
    }
    # ...
  
  Attributes:
    type: Type of the execution parameter.
    optional: Boolean value indicating whether the parameter is optional.
    use_proto: Boolean value indicating whether pb message (and other
      non-primitive types like lists) should be stored in its original form.
code: def __repr__(self):
      return (
          "ExecutionParameter(type: %s, optional: %s, use_proto: %s)"
          % (self.type, self.optional, self.use_proto)
      )
