This patch adds a GRUB_CMDLINE_LINUX_CUSTOM variable to existing cmdline options, and creates a dedicated linux_entry without theses custom cmdline options.  This allows users to switch between default and custom cmdlines options without much editing.

For example, this helps when installing a optimized tuned profile for some use cases then be allowed to choose back to the default.

An example is for drivers that needs special boot options such as:
 "rd.driver.blacklist=nouveau modprobe.blacklist=nouveau"
Installing GRUB_CMDLINE_LINUX_CUSTOM_NVIDIA in /etc/default/grub will create a boot menu to use the proprietary driver, then another one willallows to boot to the default (nouveau).
his requires a compatible driver integration

Please comment.
