What does this MR do and why?
This MR fixes the ./scripts/rspec_helpers.sh: line 127: KNAPSACK_GENERATE_REPORT: unbound variable
error by defining the KNAPSACK_GENERATE_REPORT
, FLAKY_RSPEC_GENERATE_REPORT
, and CRYSTALBALL
variables with empty values if they're not already defined. Possibly introduce by !110961 (diffs).
