I like this improvement, but 'self options' doesn't explain the idea better. This is
kind of namespace for each sub command, so simply name it as:

+	struct sd_option *options;

in a structure is enough.

And rework the comment and commit log to replace 'self option' with more meaningful
phrase such as, for e.g, "By moving the global options into individual structure as a
private member, we can solve this problem"

Also, with this patch, we can then change all those upper cased options into lower cases,
such as vdi create -P -> vdi create -p for easier typing.
