Size annotations won't work with upper case size type on k8s-coredump-handler configuration

[Heron Vieira]

Brief Description

K8s-coredump handler won't accept the size type in upper case (e.g 200K, 2M, 1G) for the annotations core_max_size, core_max_used, core_min_free. Alternatively using lower case (e.g 200k, 2m, 1g) for these annotations works.

Severity

Minor: System/Feature is usable with minor issue

Steps to Reproduce

Create a pod yml with the annotations using the size type in upper case.

annotations: {
    starlingx.io/core_pattern: "core.%P.%u.%g.%s.%t.%e",
    starlingx.io/core_max_size: 200K,
    }

Expected Behavior

The K8s-coredump handler should make the coredump respecting the configured annotations

Actual Behavior

Exception when parsing the annotations.

    Fix size configuration annotations for k8s-coredump-handler

    Fix a issue where the size configuration annotations for
    k8s-coredump-handler would throw an exception in case
    the configuration used upper case size type (e.g 200K)

    Test Plan:
    PASS: Create and crash a pod with annotations configured
          with a upper case and verify if coredump is generated
