[jira] [Work logged] (BEAM-9012) Include `-> None` on Pipeline and
PipelineOptions `__init__` methods for pytype compatibility
[ https://issues.apache.org/jira/browse/BEAM-9012?focusedWorklogId=363700&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-363700 ]

Work Description: TheNeuralBit commented on pull request #10466: [BEAM-9012] Change __init__ hints so they work with pytype
URL: https://github.com/apache/beam/pull/10466
`pytype` doesn't let you omit the `-> None` return type for `__init__` methods, nor does it let you add a hint for just a function's return type (like `# type: (...) -> None`). This PR adds full function signature type hints to the `__init__` methods for `Pipeline` and `PipelineOptions` (so far the only places I've seen issues with pytype parsing these hints).

> mypy [made a decision|https://github.com/python/mypy/issues/604] to allow init methods to omit {{\-> None}} return type annotations, but pytype has no such feature. I think we should include {{\-> None}} annotations for pytype compatibility.
