Add image_pull_secrets paameter to add_settings_to_comp for kfp v2

[revit13]

Why are these changes needed?

To address #914 a new param was added to add_settings_to_component function.

To pass the secret name the following param should be added to add_settings_to_component call:

ComponentUtils.add_settings_to_component(compute_exec_params, ONE_HOUR_SEC * 2, image_pull_secrets=["secret-name"])

Note: image_pull_secrets could not be a pipeline input parameter because they are of type PipelineParameterChannel so we get the following error when trying to use them:

  File "kfp/kfp_support_lib/kfp_v2_workflow_support/src/workflow_support/compile_utils/component.py", line 99, in add_settings_to_component
    if len(image_pull_secrets) != 0:
TypeError: object of type 'PipelineParameterChannel' has no len()

Related issue number (if any).

#914
