Title: Added basic authorization for InfluxDB if needed

When using a web server with HTTP basic authentication on it (I used nginx for proxying requests to InfluxDB) the current version of Grafana simply doesn't send the credentials with the request.
I did notice that the Graphite data source does send the credentials, so I added the same basic logic for InfluxDB as well.
