Adds Docker and requirements for scheduler and worker

[smpiano]

• Updates the pipe-tools to v4.0.0, so fixes name classes.
• AB 2.35 uses pyyaml==6 requires Loader parameter when makes yaml.load() deprecation link. Scheduler also need this, +requirements-scheduler.txt, used in tests.
• Changes base image because bash script uses pipe-bash-scripts

DRAFT:

1. port-events was tested, the job run well. The results of the data was weird compared to the current pipeline: job: https://console.cloud.google.com/dataflow/jobs/us-central1/2022-03-10_13_23_42-8687066028995394056?project=world-fishing-827

select count(*) from `scratch_matias_ttl_60_days.proto_raw_port_events_20220308`
--943669
select count(*) from `pipe_production_v20201001.proto_raw_port_events_20220308`
--983562

2. If use events_table the pipeline and not the one generated in mine scratch, the port-visits fails due to errors in JSON:
