1) Add lookback support in kernel monitor. After started, Kernel monitor will check some old logs to detect problems which happened before last node reboot. 2) Add `lookback` and `startPattern` in kernel monitor configuration. * `lookback` specifies how long time kernel monitor should look back. * `startPattern` specifies which log indicates the node is started. kernel monitor will clear all current node conditions once it finds a node start log. This makes sure that old problems won't change the node condition. 3) Add support for kernel panic monitoring, the null pointer and divide 0 kernel panic will be surfaced as event. Usually kernel monitor will report these events during looking back phase.
