Enlinkd Not Performing Bridge Topology Discovery

Description

I set up Bridge Link Discovery in a Run time env.

I got the following exception in output.log

Exception in thread "Scheduler-Thread-3-of-5" java.lang.NullPointerException

https://opennms.atlassian.net/browse/NMS-8964#icft=NMS-8964: Enlinkd Not Performing Bridge Topology Discovery

Fixed Null Pointer Exceptions
The Topolgy Discovery is scheduled only if there is
a not 0 bridge forwarding table is available
deleteNode for enlinkd is improved
Improved the scheduler to print statistics
Also checked that the BridgeTopology calculation
is done only if maxbft allows it
