Thresholdvalue in scientific notation not displayed/stored correctly

Description

Thresholding with scientific notation such as 1.0E-6 works but threshold-value is not stored correctly in database:

If you check the solution of https://opennms.atlassian.net/browse/NMS-3473#icft=NMS-3473, you will see that there is a global variable called:

org.opennms.threshd.value.decimalformat

This variable has the following default value: "##.##". If you check the documentation of DecimalFormat, you will see that in order to use properly the scientific notation, you should change it to something like this:

##.##E0

From that point, the value will be expresed in scientific notation for all Threshold Events.

You should put this variable on opennms.properties. After manually modify that file, you should restart OpenNMS.

I will update the default content of opennms.properties in order to reflect the proper usage of this variable.

9e37ac976d740017665a8ed4bd50c1bfb7ed7e79 for 1.10
