"quiet" will disable most of log messages. For debugging kdump
kernel purpose it is better to remove quiet in 2nd kernel so that
we always see kernel messages.

Use KDUMP_COMMANDLINE_REMOVE config instead of hardcode them in
kdumpctl, which makes it possible system admins decide what params to
remove such as "quiet" or other debug flags.
This patch also adds backward compatibility even if an old config is
used. It will behave the same as the old version.

For arches we do not exlictly support, kdumpctl will fail with errors because
kernel can not be found. It is caused by there's no proper KDUMP_IMG prefix
so kernel image can not be found.
Kexec/kdump functionality may simply work, so let's add those prefix in
default sysconfig file thus one can test and use kexec/kdump in Fedora.

dracut will mount rootfs for us, so we need not pass root to fstab again here.
Here remove the root-mount line.
This will depends on the root=cmdline is right, by default kdump will
inherit it from /proc/cmdline.
Vivek: add document about the assumption for the root= cmdline issue.
