Add parallelism to functional testing

[raubitsj]

Description

Adds CI parallelism to functional tests

parallelism for base (windows and linux).

Windows setup takes almost 5 minutes so this is a bit wasteful, will probably want to add caching back or move to docker cache.

Depends on:

• 0.8.4: Add split capability yea#34
• 0.8.9: Add split capability yea-wandb#92

Testing

Manual testing
