97f8c6279f Added total query time to Sherlock
This makes it easier to see if a problem is caused by slow queries or
slow Ruby code (unrelated to any SQL queries that might be used).

7f9f07023b Truncate transaction paths to 70 characters
This ensures that long URLs don't completely mess up the layout of the
table.

dec3e4ce64 Added Sherlock, a custom profiling tool for GitLab
Sherlock will be a new GitLab specific tool for measuring the
performance of Rails requests (and SideKiq jobs at some point). Some of
the things that are currently tracked:

* SQL queries along with their timings, backtraces and query plans
  (using "EXPLAIN ANALYZE" for PostgreSQL and regular "EXPLAIN" for
  MySQL)
* Timings of application files (including views) on a per line basis
* Some meta data such as the request method, path, total duration, etc

More tracking (e.g. Rugged or gitlab-shell timings) might be added in
the future.

Sherlock will replace any existing tools we have used so far (e.g.
active_record_query_trace and rack-mini-profiler), hence the
corresponding Gems have been removed from the Gemfile.

Sherlock can be enabled by starting Rails as following:

    ENABLE_SHERLOCK=1 bundle exec rails s

Recorded transactions can be found at `/sherlock/transactions`.
