Provide option to disable KDump

[Luke Hinds]

Security compliance frameworks have a requirement to disable KDump Kernel Crash Analyzer

The kdump service provides a kernel crash dump analyzer. It uses the kexec system call to boot a secondary kernel ("capture" kernel) following a system crash, which can load information from the crashed kernel for analysis.

Kernel core dumps may contain the full contents of system memory at the time of the crash. Kernel core dumps consume a considerable amount of disk space and may result in denial of service by exhausting the available space on the target file system partition. Unless the system is used for kernel development or testing, there is little need to run the kdump service.

Provide a THT / puppet class option to disable the service.

class kdump_service {

  service { 'kdump':
    ensure => 'stopped',
  }

}

Remove `crashkernel=auto` from GRUB_CMDLINE_LINUX
