Configuration via CLI flags

The pump daemon accepts configuration values via options passed directly on the commandline. Flags start with -- - for example, the port key can be set by passing --port. Camelcasing like urlPort should be replaced with - (i.e. urlPort becomes --url-port). Keys whose value is an object can be specified using . to separate nested keys. For example, the params key set to the following object:

{ "host": "localhost" }

can be set by passing localhost.

CLI flags always take precedence over everything else, including environment variables and JSON configuration files.
