This patch refactors the current codebase to be more modular
and testable. The main changes are:
- pull out all of the profile setup logic from the __init__
method to it's own method _init_nsx_profiles method to make
testing the code easier.
- refactors the nsxlib.v3 code to break out all neutron related
exceptions and cleans up the interface so we can make nsxlib.v3
it's own standalone library eventually.
To improve:
- Currently we have nsxlib.v3.dfw_api and nsxlib.v3.firewall,
we should refactor this code and merge them into one file.
- refactor nsxlib to section of each api component to it's own
subclass. For example, nsxlib().port.create() rather than
nsxlib().create_port(). I think this would be most useful
for the security group/firewall integration as there are many
methods there that are needed to interface with nsx as the security
group feature is requires the most orchestration with nsx.
Breaking them into a sub class will make things more easy to understand.
