The HOSTMAP variable is a dictionary of lists. The keys represent
roles of a server, the values represent the hostnames of machines that
fill those roles. If you are reading this, you likely know what you're
doing. If you don't know what you're doing, you probably want to put
your hostname into local_dev. Ensure it has a comma at the end, and
the hostname is a string.
 
You can get your hostname by typing `hostname` into a terminal.
