Build infrastructure changes for reporting and splitting providers

The pipeline structure of the integration test pipeline needs to be modified for simultaneous provider runs. The reporting logic also requires slight modification to report on a more granular level of pipeline actions. There is an ongoing code review that address this.

Locate the integration test pipeline structure and its reporting logic, then review the ongoing code review mentioned in the issue. Done means provider runs can execute simultaneously and reporting distinguishes pipeline actions at a more granular level.
