HBASE-27651 hbase-daemon.sh foreground_start should propagate SIGHUP and SIGTERM 

Introduce separate `trap`s for SIGHUP vs. the rest. Treat `SIGINT`, `SIGKILL`, and `EXIT` identically, as before. Use the signal name without `SIG` prefix for increased portability, as per the POSIX man page for `trap`.

`SIGTERM` handler will now honor `HBASE_STOP_TIMEOUT` as described in the file header.
