Add kernel panic and warning boot parameters #20

For kernel panics and warnings currently there are few recommendations.

In terms of configs there are CONFIG_PANIC_TIMEOUT=-1 and CONFIG_PANIC_ON_OOPS=y

In terms of sysctls there are kernel.warn_limit = 1 and kernel.oops_limit = 1`.

To complete this we can add the following boot parameters:

panic=-1
oops=panic
panic_on_warn=1

Also we can include the sysctl:

kernel.panic=-1

These should be added to cover all forms of protection.
