[openstack-dev] [neutron] Vendor Plugin Decomposition and NeutronClient vendor extension

Hi All,

It's great to see the vendor plugin decomposition spec[1] finally getting
merged!  Now that the spec is completed, I have a question on how this may
impact neutronclient, and in particular, its handling of vendor extensions.

One of the great things about splitting out the plugins is that it will
allow vendors to implement vendor extensions more rapidly.  Looking at the
neutronclient code, however, it seems that these vendor extension commands
are embedded inside the project, and doesn't seem easily extensible.  It
feels natural that, now that neutron vendor code is split out,
neutronclient should also do the same.

Of course, you could always fork neutronclient yourself, but I'm wondering
if there is any plan on improving this.  Admittedly, I don't have a great
solution myself but I'm thinking something along the line of allowing
neutronclient to load commands from an external directory.  I am not
familiar enough with neutronclient to know if there are technical
limitation to what I'm suggesting, but I would love to hear thoughts of
others on this.

Thanks in advance!

Best,
Ryu
