Monitor a program and resume it when it dies, either exiting abnormally or killed by OOM in linux.

Usage:
./forever /usr/bin/BINARY_NAME options
Example:
CWD=./myproject/ ./forever ~/.nvm/versions/node/v8.14.0/bin/node server.js -t

Note:
Make sure monitor the right process, the executable, don't exit. Cause we will monitor its pid.
