Justin Hammond 4cdccd69a4 Update common network type consts to same origin
This patch removes new definitions of common network type constants (TYPE_FLAT,
TYPE_LOCAL, etc.) and modifies uses of aforementioned constants to a common
place where constants are defined (neutron.plugins.common.constants). This
patch does not change values that are equal in value but different in name:
NETWORK_TYPE_FLAT vs TYPE_FLAT. A second changeset will be made to handle that
case.

Unit tests were modified as well when they referred to the constant.

Finally, the ovs agent code refers to the OVS plugin constants directly and
these had to be changed as well. A TODO flag was put in that file due to use
of another plugin specific constant.

Network types that were only defined in a single plugin, such as mellanox's
infiniband (IB) network type was not carried over to the common constants file.

Fixes-bug: #1196170
