autoconfig: avoid renaming hostnames in nagios
Auto Config tries to use the output of 'hostname' command as a host_name for node in nagios. But if the hostnames are not unique, then it uses IP Address as node_name name in nagios. If after removal of a node, hostnames becomes unique then auto config renames all the host configuration in nagios to their hostnames instead of ip address. It creates multiples issues like removing all the nodes, loss of time series data and unnecessary confusion to the user. Fixing this issue by retaining the perviously configured host names always by going through the host uuid. So if duplication comes after a node addition then only that node will be configured with ip address as host_name but all other existing hosts will not be touched. Similary, even though there is no duplication after the removal of a node with duplicate name, auto config will retain the previously configured hostnames (which are ip addresss becasue there was a hostname duplication earlier) instead of renaming.
