fix openroadm deprecated methods

Some OpenROADM RPCs are now deprecated, what generates many warnings during Tpce builds.
They should be replaced by their newer equivalent.

$ grep WARN mvn.log.0 | grep 181130 | cut -d] -f3 | sort | wc -l
103

Most of them are caused by the ODL YANG  sources generator automated process and must be ignored
But none all of them are concerned.

$ grep WARN mvn.log.0 | grep 181130| grep -v generated-sources | cut -d] -f3 | sort | wc -l
22

$ grep WARN mvn.log.0 | grep 181130| grep -v generated-sources | cut -d] -f3 | sort | uniq -c | sort -k1,1nr | sed 's/ has been deprecated//'
