[PATCH v4 3/4] kdump.sysconfig: add the kdump logger configurations

[Lianbo Jiang]

The kdump logger has the default values of the log levels, but
sometimes, need to change the value of log level in order to
get more debugging messages for troubleshooting.

Here, user will have a chance to reconfigure it.
