Metric Prefix should end with a dot by default ?

[snirad]

looking at telegraf default config, we can see that he seperate the metric by a dot. if you define a Prefix with go-statsd, you have to add a dot at the end or else telegraf will not move it on.

should we add dot at the end of the prefix by default ?

@snirad I don't think adding a dot is good as some users might not need it. I think we can make docs more clear by providing example with the dot.
