[AWIPS #KLE-673390]: EDEX Latency Issues

The default purge rules for any product not specified in a decoder purge file 
is taken from

/awips2/edex/data/utility/common_static/base/purge/defaultPurgeRules.xml

You will need to add a purge rule to the file

/awips2/edex/data/utility/common_static/base/purge/satellitePurgeRules.xml

and restart EDEX for it to take effect.  The syntax should be

<rule>
        <keyValue>CONUS</keyValue>
        <keyValue>DHR</keyValue>
        <versionsToKeep>60</versionsToKeep>
</rule>

Notice at the top of that file, 
<key>sectorID</key>
<key>physicalElement</key>

SectorID for all Unidata FNEXRAD composites is "CONUS" and the physicalElement 
key must match what is in

https://github.com/Unidata/awips2/blob/upc/edexOsgi/com.raytheon.edex.plugin.satellite/res/scripts/physicalElements.sql

In the case of FNEXRAD products it's simply the product identifier (DHR, DVL, 
HHC, etc)

By the way, I'll add these purge rules by default.  How many frames back is 
ideal for you?
