This is the base class, FibreChannelDriver, for all fibre channel
drivers to extend. Currently, it has only initialize_connection
with comments, but this will be a place to put common functions
similar to the iSCSI base class.
This patch depends on the following nova and devstack changes
to be functional(both still in the review process but approved
for Grizzly):
https://review.openstack.org/#/c/19992/
https://review.openstack.org/#/c/20003/
This patch does not support copy_image_to_volume and
copy_volume_to_image in the Grizzly release. We'll revisit
this in Havana and add that support.
