Timestamp reports

[osmolyar]

Is your feature request related to a problem? Please describe. Currently reports are named according to the Feature file, and overwritten each time the Feature file is run.

Describe the solution you'd like It would be nice to have a timestamp added to the file name to keep a record of prior reports.

Describe alternatives you've considered Something like the following

 onRunnerEnd() {
        const jsonFolder = (0, path_1.resolve)(process.cwd(), this.options.jsonFolder);
        const date = new Date().getTime()
        const jsonFile = (0, path_1.resolve)(jsonFolder, `${this.report.feature.id}_${date}.json`);
        const json = [this.report.feature];
        const output = (0, fs_extra_1.existsSync)(jsonFile) ? json.concat((0, fs_extra_1.readJsonSync)(jsonFile)) : json;
        (0, fs_extra_1.outputJsonSync)(jsonFile, output);
    }
