TFX on Cloud AI Platform Pipelines: kfp not installed by default

[Jani Patokallio]

In Lab 02, for "Validate lab package version installation", the kfp package is not installed by default:

TFX version: 0.26.3
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'kfp'

Fortunately the suggested %pip install --upgrade --user kfp==1.0.4 command works.
