[Bug]: Support error handling in PyTransform

[Polber]

What happened?

Beam YAML's PyTransform does not allow a caller to specify error_handling similar to other turnkey transforms.

One would expect the following to work:

- type: PyTransform
  name: Transform
  config:
    constructor: __callable__
    kwargs:
      source: |
        def process(pcoll):
          return pcoll | beam.Map(lambda row: row.line)
    error_handling:
      output: errors
