Milestone 9: Build performance test report view

[ninetteadhikari]

This PR is for "Milestone 9: Build performance test report view" as stated in the Scope of Work. It addresses the following:

• Add Apache echart library to create oe build performance report charts.
• Restructure data to time and value array format to be used by echarts. It also converts test duration to minutes and adds zoom to the line charts.
• Update measurement statistics data to include start_time so that time can be displayed instead of commit numbers on the chart. It also updates default commit history length to 300.
• Add styling updates including labels for x and y axis, tooltip, and section descriptions.

Local Setup

In the poky repository run the following to build the report HTML:

./scripts/oe-build-perf-report -r "LOCAL_PATH_TO_YOCTO_BUILDSTATS" --branch "master" --commit "663f1805742ff6fb6955719d0ab7846a425debcf" --branch2 "master" --html > test.html

Note:

• Add your local path to the yocto-buildstats repo
• The above command builds the report in a file called test.html. You can access it in the root directory in poky.
