Prerequisite for the replacement:

• Feature parity between PALite and PALM
• Check/validations parity between PALite and PALM

Replace PALM with PALite for disagg testing:

• Python tests (test suite)
• Stress tests:
  • test/format
  • test/checkpoint
• test/model
• Evergreen tasks

Replacement steps:

1. Enable PALite for relevant tests
2. Run both PALM and PALite in parallel
3. Fix discovered issues with PALite: feature gaps, validations gaps
4. Remove PALM
5. [Optional] Rename PALite to PALM
