Add a special START_SERVER_JVMFLAGS option only for `start` command to distinguish JVMFLAGS and SERVER_JVMFLAGS.
If we use the normal way to add JVM options with `JVMFLAGS` in `conf/java.env`, then it will effect almost all shell scripts under `bin` directory. Even if using `SERVER_JVMFLAGS` will effect some commands like `zkServer.sh status`, include four-letters commands.
For example, if the JVMFLAGS is
```bash
export JVMFLAGS="-Xms3G -Xmx3G -Xmn1G -XX:AlwaysPreTouch -XX:CMSInitiatingOccupancyFraction=70 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+PrintGCDetails -XX:-PrintGCTimeStamps -Xloggc:/home/zookeeper/logs/zookeeper_`date '%Y%m%d%H%M%S'`.gc -XX:-UseGCLogFileRotation -XX:NumberOfGCLogFiles=10 -XX:GCLogFileSize=64M"
```
then we will get too many GC log files due to using the `mntr` four-letters command regularly in some monitor situation.
```bash
$ ls ~/logs
zookeeper_20170704175942.gc
zookeeper_20170704180101.gc
zookeeper_20170704180201.gc
zookeeper_20170704180301.gc
zookeeper_20170704180401.gc
...
```
