In the /etc/sysconfig/kdump, we usually use the uppercase configuration
name for all options. So let's use the same method to handle this.

Let's add the rd.kdumploglvl option to control log level in the second
kernel, which can make us avoid rebuilding the kdump initramfs after we
change the log level in /etc/sysconfig/kdump.

The kdump-logger will be used by the system service(daemons), so let's
appropriately convert the logger numeric level to syslog level with the
facility(daemon). The number is constructed by multiplying the facility
by 8 and then adding the level.
About The Syslog Protocol, please refer to the RFC5424 for more details.

Previously, the range of log level is from 1 to 6, and the TRACE
level and FATAL level are not used, therefore, let's remove these
unused log levels.
Now it has only four log levels: error(1), warn(2), info(3)
and debug(4). We have to remap the numeric log level to the logger
priority or syslog log level, which is finished in kdump-logger.sh
module, it is invisible for user.

Let's add sanity checks for the log levels in order to avoid
passing illegal log levels to the logger.

Currently, all messages are directly printed to the console, sometimes,
we also need to output these messages to the journal log according to
the log level.
In view of this, introduce the kdump logger from the dracut module.
