using Serilog.Settings.AppSettings and Serilog.Sinks.Datadog.Logs

entry in App.config causes exception:

	<add key="serilog:write-to:DatadogLogs.tags" value="name:ZA2-FUNDSTI1;client:IRESS;owner:Trading;key:trading-production-za;application:FundsTradingInterface" />

I can make pull request to fix it but can't push for some reason
