Add jitter data to InfluxDB feed

Also add the upload/download bits to fix #82, this adds an explicit download_bits and upload_bits to the results.

Since we're not changing the DDL we don't want to add the fields to the Create method when executing a speedtest. We can however update the influx method to pull that data out of the data column which houses everything produced by the cli.

You'll want to make a couple changes...

1. Remove all changes from App/Jobs/ExecSpeedtest.php
2. Add 'data' => 'array' under 'scheduled' => 'boolean' in App/Models/Result so we can access the casted values
3. Where you're referencing values from the data column in App/Models/Result you can now do that like so $this->data['ping']['jitter']

See comment in conversations on accessing information stored in the data column.

Also just a heads up, you'll want to update your branch as I've added branch protections to ensure basic testing and code quality.
