Improve soak graphs and content

+ Fix duration, mention number of tests and runs.
- Hover information still feels wrong.
+ Mention "critical rate" instead of "throughput" where possible.
+ Mention lower bounds are displayed.
+ Rename "plrsearch_algorithm" label to "PLRsearch".
  + Because the previous link did not work. Due to underscore?
+ Rename "SOAK" to "soak" or "Soak" (except when it is a tag).

 Soak Tests
 ==========
 
-Long duration soak tests are executed using `plrsearch_algorithm`_.
+Long duration (2 hours per test) soak tests are executed
+using `PLRsearch`_ algorithm. As the test take long time, only 10 test
+were executed, two runs each.
