[BEAM-759] Implement wait_until_finish method for existing runners.
Implement wait_until_finish method for existing runners.
Also defines the not implemented cancel() method and updates existing
usages to use wait_until_finish() instead of blocking runners.
Main changes are in the runners/ folder
runner.py - has the APIs
dataflow_runner.py, direct_runner.py modified to implement the API (moving
the existing blocking code around.)
Rest of the changes are mechanical to mainly convert
p.run() to p.run().wait_until_finish() in tests and examples. Changed tests
because they run validation after the run and need to block until completion.
We may revert the changes in examples. I converted the because in the
instructions we directed users to blocking runners before and this change keeps
the behavior same.
I have started a local post commit run (not completed yet) and it was
successful with the first few tests so far and the changes are same for all
tests.
Remaining work after this PR:
- Removing BlockingDataflowRunner. It is not used after this change with
the SDK code/examples/tests.
- Support for duration argument in wait_until_finish is missing.
