how does one specify the '/' symbol in a quartz cron trigger uri? normally it means the following:
The '/' character is used to specify increments. For example "0/15" in the seconds field means "the seconds 0, 15, 30, and 45". And "5/15" in the seconds field means "the seconds 5, 20, 35, and 50". You can also specify '/' after the '*' character - in this case '*' is equivalent to having '0' before the '/'. (http://quartz.sourceforge.net/javadoc/org/quartz/CronTrigger.html) but the camel-quartz endpoint uri syntax redefines / to mean a space so we can no longer specify this type of cron expression with the quartz endpoint.
