Public bug reported:

Since Xenial release, Ubuntu relies on systemd as its init system -
there's a kdump service to prevent some other services to unnecessarily
start in kdump environment.

Problem: if we add something to KDUMP_CMDLINE_APPEND, the entry for
kdump service, "systemd.unit=kdump-tools.service" is removed from the
command-line. The user manually needs to add that, and this seems highly
prone to error.

We propose here to decouple the "systemd.unit=kdump-tools.service"
parameter from KDUMP_CMDLINE_APPEND, so if user wants really to remove
this option, they should used KDUMP_CMDLINE instead.
