Error description

• The HuaweiM2K collector and domain to discover the RAN were
  configured using locally placed topology XML files.
  
  As soon
  as we start discovery, the HuaweiM2K collector throws below
  exception and does not process the XML files and exits
  immediately.

Local fix

• Root cause of the issue: collector is expecting below
  properties in properties file supplied
  (HuaweiM2KCollector.properties or
  properties file supplied as
  -propsFile value during the collector startup).
  
  1)
  processor.enb.srannbi.netype=<value>
  2)
  processor.enb.srannbi.neversion=<value>
  3)
  processor.enb.srannbi.combinedsite.netype=<value>
  4)
  processor.enb.srannbi.combinedsite.neversion=<value>
  
  
  Collector is throwing exception when it doesn't find these
  entries (all 4 needed) and exiting the rest of collection
  process.
  
  But in the meanwhile, to get rid of the issue, we
  can add the above entries with some dummy values like below.
  
  pr
  ocessor.enb.srannbi.netype=NA
  processor.enb.srannbi.neversion=NA
  
  processor.enb.srannbi.combinedsite.netype=NA
  processor.enb.sran
  nbi.combinedsite.neversion=N
