Run with hugepages

Set HW_HUGEPAGE_BYTES for jobs that need hugepage-backed memory.

hugepage-tests:
  stage: test
  tags:
    - saas-linux-large-amd64
  variables:
    HW_HUGEPAGE_BYTES: "1073741824"
    HW_NUMA_POLICY: "single-node"
  script:
    - ./run-hugepage-tests.sh

Use HW_NUMA_POLICY when hugepage locality matters.
