Fix Blueprint export handling of properties containing nameservice references

This patch implements a fix for AMBARI-7458.

This patch updates the BlueprintConfigurationProcessor such
  that properties that can contain a namservice reference (there
  are only two known properties at this point) are not removed by
  the BlueprintConfigurationProcessor during the export process.

Previously, these properties were removed, since they didn't contain
  hostname information. In a NameNode HA scenario, these particular
  properties will reference nameservices, so this problem would only
  occur when NameNode HA is enabled.

This patch addresses the immediate problem, but in the longer-term
  the stack definitions should be updated to include HA-related
  metadata, so that the Blueprint processor can determine which
  properties are modified in an HA scenario.

This patch also implements a new unit test to verify this change.
