erasure-code: HTML display of benchmark results

The ceph_erasure_code_benchmark output is converted into a JSON series suitable to display in HTML with the http://www.flotcharts.org/ library. A self contained copy of the HTML,JS,CSS files is included for durability and can be used from the source tree with: CEPH_ERASURE_CODE_BENCHMARK=src/ceph_erasure_code_benchmark \ PLUGIN_DIRECTORY=src/.libs \ qa/workunits/erasure-code/bench.sh fplot jerasure | tee qa/workunits/erasure-code/bench.js and display with: firefox qa/workunits/erasure-code/bench.html Signed-off-by: Loic Dachary <loic@dachary.org>
