✨ Add prefix option to config (#3)

* Added prefix option to set the hostname.

* updated README.md to include the prefix option and description.

* added entry to 30-influxdb.sh for the prefix option.

* changed the default value of prefix to localhost to map to the glances grafana dashboard.

* changed the prefix order and moved it to the end of the 30-influxdb.sh...because it did not work above it in the conf possibly?

* Changed the default to indicate localhost for the glances dashboard.

* Changed the sample to include the prefix localhost.
