Performance bar uses Sherlock for formatting queries, but the performance bar doesn't display whitespace

Our custom performance bar code does this:

def track_query(raw_query, bindings, start, finish)
  query = Gitlab::Sherlock::Query.new(raw_query, start, finish)
  query_info = { duration: query.duration.round(3), sql: query.formatted_query }
                                                                                 
  PEEK_DB_CLIENT.query_details << query_info
end

Specifically:

query = Gitlab::Sherlock::Query.new(raw_query, start, finish)

Every instance of Gitlab::Sherlock::Query will generate a Ruby backtrace using caller_locations, which is quite slow (especially for a lot of queries).

Further we use #formatted_query in an attempt to display the SQL in a more readable manner. Unfortunately the performance bar displays the queries without newlines, probably as the result of using <pre> without the right CSS settings.
