--------------------------------
    Request participants:   (was: )
             Description: 
The program can not get the correct version when we installed Ranger KMS based 
on the latest version. Now the code logical is as follows:
if [ -f ${PWD}/version ] 
then
        VERSION=`cat ${PWD}/version`
else
        VERSION="0.5.0"
fi
Now the version file does not exist. VERSION can only be equal to 0.5.0. 
We should add version file into kms install path. The current version should be 
writed in the version file.

  was:
An incorrect rollback point was created when we installed Ranger KMS based on 
the latest version. The reason is as follows:
Create rollback point logic code is as follows:
create_rollback_point() {
    DATE=`date`
    BAK_FILE=$APP-$VERSION.$DATE.bak
    log "Creating backup file : $BAK_FILE"
    cp "$APP" "$BAK_FILE"
}
Variable VERSION assignment logic is as follows:
if [ -f ${PWD}/version ] 
then
        VERSION=`cat ${PWD}/version`
else
        VERSION="0.5.0"
fi
Now the version file does not exist. VERSION can only be equal to 0.5.0. The 
current version is 0.7.0-SNAPSHOT. 
We should add version file into kms install path. The current version should be 
writed in the version file.

                 Summary: The program can not get the correct version when we 
installed Ranger KMS based on the latest version  (was: An incorrect rollback 
point was created when we installed Ranger KMS based on the latest version)
