Add ability to run performance regression checks on Beam IO Load tests.

[pranavbhandari24]

This PR adds ability to run regression checks against Beam IO load tests.

Below is the command to run this,

python3 apache_beam/testing/analyzers/load_test_perf_analysis.py --config_file_path=apache_beam/testing/analyzers/io_tests_config.yaml

We can automate runs for these regression checks by adding a GH workflow in a separate PR.

Merging because of the previous approvals

[damccorm]

Not a big deal, but in general we should wait for all checks to pass before merging
