The goal is a simple(r) way of overriding plugins or attributes via the command-line so that it's not necessary to create YAML configs for each combination you need to run.

One initial thought is that we create a -o with a key/value pair option similar to the -D java override. e.g. aminate -oaminator.plugins.blockdevice.linux.device_prefixes=[xvd, sd]

What this will do is override the values of any of the config values that are normally specified in the YAML (so it will need to run after plugins are loaded)

@mtripoli may be able to add additional context for a better example
