AllowDuplicateNodes to True will allow to import duplicated node if exists on other polling engine.
Example:
- you have already node with IP 1.1.1.1 monitored on engine 1
- run discovery on engine 2 and it finds another node with IP 1.1.1.1 (it can be the same or other node)
- if this settings is true then discovery imports it otherwise not
Orion will de-duplicate nodes already discovered through Discovery profile in case of importing through SDK.
