First attempt at getting influxdb installed as part of container build.
Satisfy dependencies for installation of influx-db.
Config file for influxdb was broken: bind IP was missing. Added slighly altered latest version of config from https://github.com/influxdb/influxdb/blob/master/config.sample.toml.
Ports necessary to make influxdb useful from outside world should be mapped forwarded by Vagrant.

We also should have a host-only type network to make communication with the VM easier. Forwarded ports should be accessible on the host via `localhost:<port>`.

Running influxdb from directory other than current causes problems with relative pathing in the config file.
