    kdumpctl: Add kdumpctl estimate

    Add a rough esitimation support, currently, following memory usage are
    checked by this sub command:

    - System RAM
    - Kdump Initramfs size
    - Kdump Kernel image size
    - Kdump Kernel module size
    - Kdump userspace user and other runtime allocated memory (currently
      simply using a fixed value: 64M)
    - LUKS encryption memory usage

    The output of kdumpctl estimate looks like this:
      # kdumpctl estimate
      Reserved crashkernel:    256M
      Recommanded crashkernel: 160M

      Kernel image size:   47M
      Kernel modules size: 12M
      Initramfs size:      19M
      Runtime reservation: 64M
      Large modules:
          xfs: 1892352
          nouveau: 2318336

    And if the kdump target is encrypted:
      # kdumpctl estimate
      Encrypted kdump target requires extra memory, assuming using the keyslot with minimun memory requirement

      Reserved crashkernel:    256M
      Recommanded crashkernel: 655M

      Kernel image size:   47M
      Kernel modules size: 12M
      Initramfs size:      19M
      Runtime reservation: 64M
      LUKS required size:  512M
      Large modules:
          xfs: 1892352
          nouveau: 2318336
      WARNING: Current crashkernel size is lower than recommanded size 655M.

    The "Recommanded" value is calculated based on memory usages mentioned
    above, and will be adjusted accodingly to be no less than the value provided
    by kdump_get_arch_recommend_size.
