run_pipeline discards needed parameters

azure-devops/azure/devops/v6_0/pipelines/pipelines_client.py takes the parameter run_parameters and then sets the variable content via

        content = self._serialize.body(run_parameters, 'RunPipelineParameters')

In doing so it discards templateParameters (along with previewRun, stagesToSkip, and yamlOverride), but my concern is with templateParameters.

If I'm tracing things correctly, the problem is in the class RunPipelineParameters in azure-devops/azure/devops/v6_0/pipelines/models.py which only maps resources and variables:

class RunPipelineParameters(Model):
    """
    :param resources:
    :type resources: :class:`RunResourcesParameters <azure.devops.v6_0.pipelines.models.RunResourcesParameters>`
    :param variables:
    :type variables: dict
    """

    _attribute_map = {
        'resources': {'key': 'resources', 'type': 'RunResourcesParameters'},
        'variables': {'key': 'variables', 'type': '{Variable}'}
    }

    def __init__(self, resources=None, variables=None):
        super(RunPipelineParameters, self).__init__()
        self.resources = resources
        self.variables = variables

Read azure-devops/azure/devops/v6_0/pipelines/models.py and the run_pipeline entry point in azure-devops/azure/devops/v6_0/pipelines/pipelines_client.py. Compare RunPipelineParameters with the parameters described in the issue, then trace how it is serialized. Done means templateParameters and the other listed run options are preserved when run_pipeline builds its request.
