Parse a compound arg string like --option foo=bar,baz=12. This is

A command line argument like --disk just extends this interface
and calls add_arg a bunch to register subarguments like path=,
size=, etc. See existing impls examples of how to do all sorts of
crazy stuff.
Class parameters:
@guest_propname: The property name in the Guest class that tracks
the object type that backs this parser. For example, the --sound
option maps to DeviceSound, which on the guest class is at
guest.devices.sound, so guest_propname = "devices.sound"
@remove_first: List of parameters to peel off the front of the
option string, and store in the optdict. So:
remove_first=["char_type"] for --serial pty,foo=bar
maps to {"char_type", "pty", "foo": "bar"}
@stub_none: If the parsed option string is just 'none', make it a no-op.
This helps us be backwards compatible: for example, --rng none is
a no-op, but one day we decide to add an rng device by default to
certain VMs, and --rng none is extended to handle that. --rng none
can be added to users command lines and it will give the expected
results regardless of the virt-install version.
