Subject: [PATCH] scripts: Add Additional Kustomization For Baremetal
 Deployment

Adding an option to inject additional EDPM variables for baremetal
deployments using Kustomize.
The following variables were added:
  - EDPM_BAREMETAL_KERNEL_ARGS, uses `edpm-kernel` role to modify kernel
    arugments
  - EDPM_BAREMETAL_KERNEL_HUGEPAGES, uses `edpm-kernel` role to
    configure hugepages
  - EDPM_BAREMETAL_TUNED_PROFILE, uses `edpm_tuned`
    role to configure a tuned profile
  - EDPM_BAREMETAL_TUNED_ISOLATED_CORES, uses `edpm_tuned` role to
    configured tuned isolated cores
  - EDPM_BAREMETAL_NETWORK_CONFIG_OVERRIDE, uses `edpm_network_config`
    role to allow providing custom network configuration
