Permit to detect more error message
When the kernel has started, the pattern used to detect problems are hardcoded in lava_common/constants.py like KERNEL_PANIC_MSG. Adding more pattern is so hard (need to modify source code). For example, I want to add "GXL:BL1:" for detecting when an amlogic reset to uboot during a boot..
A way to change it (like uboot error messages) is needed.
