test: provide timing information

[vemv]

Fixes #755

With these changes, responses are now enhanced with the following structural changes:

+{:elapsed-time {:humanized "Completed in 1028 ms", :ms 1028},
+ :ns-elapsed-time
+ {:failing-test-ns {:humanized "Completed in 1026 ms", :ms 1026}},
 :summary {:error 0, :fail 2, :ns 1, :pass 0, :test 2, :var 2},
 :testing-ns "failing-test-ns",
 :gen-input [],
 :status #{"done"},
 :id "52816a02-86cc-457a-a9fa-b287e90da189",
 :session #{"e3b12907-d64e-4e6d-902a-ab63fef9c811"},
 :results
 {:failing-test-ns
  {:fast-failing-test
   [{:index 0,
     :ns "failing-test-ns",
     :file "failing_test_ns.clj",
     :type "fail",
     :diffs [["1\n" ["0\n" "1\n"]]],
     :line 5,
     :var "fast-failing-test",
     :expected "0\n",
     :context [],
+    :elapsed-time {:humanized "Completed in 20 ms", :ms 20},
     :actual "1\n",
     :message ""}],
   :slow-failing-test
   [{:index 0,
     :ns "failing-test-ns",
     :file "failing_test_ns.clj",
     :type "fail",
     :diffs [["1\n" ["0\n" "1\n"]]],
     :line 9,
     :var "slow-failing-test",
     :expected "0\n",
     :context [],
+    :elapsed-time {:humanized "Completed in 1006 ms", :ms 1006},
     :actual "1\n",
     :message ""}]}}}

I'd probably use names like :elapsed-time and :elapsed-time-string/humanized, as I find the use of took confusing. Other terms that come to mind duration, time, etc. I recall prepl just uses the :ms key, so I can live with something like this as well.

[bbatsov]

As this is already under :timing you can also simply go with :ms and :humanized. Perhaps :timing can become :elapsed-time or :duration?

Other than my remark about the naming - everything looks good.

[vemv]

All set!

I also updated the PR desc with the new names and the newly implemented global key.

I ran lein docs so these showed up.

Guess Roman forgot to run this.

I've cut v0.32.0-alpha2 to play with this cider.el side
