@grafana/e2e: API improvements (#23079)

* Minor changes

* Fixtures path is now relative to the project directory

* URL support module now has individual exports

* Scenario context timing issues resolved

... caused by being ran synchronously, instead of as part of Cypress' asynchronous queue.

* Scenario context API now supports multiple keys per function call

* addDataSource flow accepts a config argument

… and optionally checks datasource health status

* Added readProvisions command

* Added addPanel flow
