Integration tests for benchmark API.

- Randomized integration tests for the benchmark API.
- Negative tests for cases where the cluster cannot run benchmarks.
- Return 404 on missing benchmark name.
- Allow to specify 'types' as an array in the JSON syntax when describing a benchmark competition.
- Don't record slowest for single-request competitions.

 There are several parameters which may be set at the competition level:
 [horizontal]
-`name`::            Unique name for the competition
-`iterations`::      Number of times to run the competitors
-`concurrency`::     Within each iteration use this level of parallelism
-`multiplier`::      Within each iteration run the query this many times
-`warmup`::          Perform warmup of query
-`num_slowest`::     Record N slowest queries
-`search_type`::     Type of search, e.g. "query_then_fetch", "dfs_query_then_fetch", "count" 
-`requests`::        Query DSL describing search requests
-`clear_caches`::    Whether caches should be cleared on each iteration, and if so, how
-`indices`::         Array of indices (and optional types) to search, e.g. ["my_index_1/my_type_1", "my_index_2", "my_index_3/my_type_3"]
+`name`::            Unique name for the competition.
+`iterations`::      Number of times to run the competitors. Defaults to `5`.

 Cache clearing parameters:
 [horizontal]

 `num_executor_nodes`::      Number of cluster nodes from which to submit and time benchmarks. Allows user to run a benchmark simultaneously on one or more nodes and compare timings. Note that this does not control how many nodes a search request will actually execute on. Defaults to: 1.
-`percentiles`::             Array of percentile values to report. Defaults to: [10, 25, 50, 75, 90, 99]
