K8s Coredump Handler - Change default handler

Browse Source 
Change default handler to k8s-coredump-handler
on kernel.core_pattern.

Test Plan:
PASS: Install and bootstrap system
PASS: Verify if kernel.core_pattern is changed
      to k8s-coredump-handler after bootstrap
PASS: Validate feature in a Backup and Restore,
      checking if kernel.core_pattern is changed
      to k8s-coredump-handler after restore.
PASS: Validate feature in a DC environment,
      checking if kernel.core_pattern is changed
      to k8s-coredump-handler in both
      the controllers and subclouds after install.

Regression:

PASS: After bootstrap, create and crash a pod with
      annotations configured and verify if coredump
      is generated on pod namespace.
PASS: After bootstrap, crash a non k8s application
      and verify that the coredump is generated as
      previously (by systemd-coredump)
PASS: Before bootstrap, crash a non k8s application
      and verify that the coredump is generated as
      previously (by systemd-coredump)
PASS: Validate feature in a Backup and Restore,
      creating and crashing a pod with annotations
      configured and also crashing a non k8s
      application, and verify if the coredump
      was generated correctly.
