Store build information in a file

[llxia]

BuildStatus.jsx contains information of builds that TRSS needs to monitor in dashboard (not insert into db).

 OpenJ9: {
        url: "https://ci.eclipse.org/openj9/",
        builds: [
            "Pipeline-Build-Test-All",
            "Pipeline-Build-Test-JDK8-linux_390-64_cmprssptrs",
...

Instead of keeping these information in *.js, we should keep it in a .json file. In this way, change the information does not require re-build and each user can have their own file.
