XDCR - Log statements shouldn't contain newline character in between

Support brought to my attention that they would like to use some log parser tools for parsing the server logs. But goxdcr has some log statements which has \n, which apparently hinders the log parsing through the tool they use. Eg: https://github.com/couchbase/goxdcr/blob/335aac21defca1c9ca9685d04b83c1fdb61f8ee4/resource_manager/resource_manager.go#L629
