Bug Report

What did you do?

Gave Prometheus a query like some_query[ 5s]. Note the space after the bracket.

What did you expect to see?
The query get's parsed to the same as some_query[5s] (without space).

What did you see instead? Under which circumstances?

Error executing query: invalid parameter 'query': parse error at char 12: missing unit character in duration
