Datadog api key is leaking into logs in default config

[SleepyBrett]

Starting up the software with no configuration overrides etc. places logging into debug mode which results in log messages like this:

time="2018-08-24T20:13:02Z" level=debug msg="POSTed successfully" action=flush endpoint="https://app.datadoghq.com/api/v1/series?api_key=<MY ACTUAL API KEY>" request_headers="map[Content-Encoding:[deflate] Traceid:[7918023244848592696] Parentid:[3942115212271789064] Spanid:[1544772588644824963] Resource:[flush] Content-Type:[application/json]]" request_length=29313 response="{\"status\": \"ok\"}" response_headers="map[Content-Length:[16] Dd-Pool:[propjoe] X-Content-Type-Options:[nosniff] Strict-Transport-Security:[max-age=15724800;] Date:[Fri, 24 Aug 2018 20:13:02 GMT] Content-Type:[text/json]]" status="202 Accepted"

While I think there is some value in outputting the datadog apikey in a debug message I think that both for security and sanity that logging should probably not be set to debug level by default. Or that examples like this one (https://varnull.adityamukerjee.net/2018/04/05/observing-kubernetes-services-with-veneur/) should probably show how to override the log level.

Thanks for the heads-up!
