Loki test adjustments

We very regularly see pipeline related related timeouts with Loki, whether from pods not coming up or cypress timeouts. This issue is to evaluate the current Loki tests and determine where improvements can be made.

Considerations:

• Test SimpleScalable at package test-values; but SingleBinary on Umbrella to reduce all-packages utiliztion
• Modify Cypress testing retries and timeouts
  • runMode: 2 ==> runMode: 30
  • Reduce timeout: 30000 and cy.wait(10000) to something smaller, possibly 5000
