Cole Robinson 41a84bae9f cli: Rework adhoc CLI parsing into a class structure
This adds:

VirtCLIArgument: a single foo=bar mapping
VirtOptionString: A collection of VirtCLIArguments, that parses the whole thing
VirtCLIParser: Represents a single cli option like --disk, --network, etc.

Centralizing this infrastructure opens up a lot of doors for future
improvements, like cli option introspection.
