NMS-6300: Add event definitions for newer F5 traps
NMS-6301: Improvements to F5 SNMP data collection
Rename GTM-related F5 data collection groups (were incorrectly labeled LTM)
datacollection configs changed, update test to match them
bump selenium version, refactor the test base a bit
NMS-6305: Add 64-bit SNMP ifXTable packet counters for unicast, multicast, broadcast
Fix for NMS-6302 - SnmpInterfaceRrdMigrator breaks with "javax.xml.bind.UnmarshalException: inf"

Now all the Long/Double values as a special adapter to properly parse:
inf, -inf, u, nan, with or without spaces in between.

Threre is a new JUnit test for the RRD that was failing with "inf".
Fixing DataCollectionConfigParserTest

$ grep "[<]group " etc/datacollection/* | wc -l
     260

1 group has been added since, so all the test that refers to a group
count has been updated.
