Removed E125 (continuation line does not distinguish itself
from next logical line) from the ignore list and fixed all
the indentation issues. Didn't think it was going to be
close to 100 files when I started.

The functionality within neutron.db.common_db_mixin is available via
neutron-lib APIs. This patch removes common_db_mixin and updates any
uses of it to use neutron-lib instead.

according to https://wiki.openstack.org/wiki/Python3,
now we should avoid using six.iteritems and replace
it with dict.items.

Neutron-lib 1.1.0 is now out and contains the provider
network API definition (as per commit [1]). This patch
moves neutron references over to the neutron-lib
version.

- Consumers using the public constants within neutron's
providernet API extension must now use the values
from neutron-lib.

In routed provider networks, a network can be divided by segments and
each segment will have its own DHCP agent. AutoScheduling for networks
exists. This patchset is for enabling auto scheduling for routed
networks.

There is a bug in pep8, when 'select' used, it omits all default checks
and runs only those specified by 'select'. We got hit by this issue
since I2d26534230ffe5d01aa0aab6ec902f81cfba774d was merged which lead to
almost no static checks in pep8 job.
Also note that off_by_default decorator has no effect for now because
factory in hacking is triggered after ignored checks are collected.
There will be a follow-up patch for that in order to make pep8 doing
its job quickly.

This patch set is for breaking the circular dependency between
Agent/NetworkDhcpAgentBinding. The goal of this is to implement
Agent OVO

Currently neutron DCHP scheduler assumes that that every server running
a dhcp-agent can reach every network. Typically the scheduler can
wrongly schedule a vlan network on a dhcp-agent that has no reachability
to the network it's supposed to serve (ex: network's physical_network
not supported).
Typically such usecase can append if:
* physical_networks are dedicated to a specific service and we don't
want to mix dnsmasqs related to different services (for
isolation/configuration purpose),
* physical_networks are dedicated to a specific rack (see example
diagram http://i.imgur.com/NTBxRxk.png), the rack interconnection can
be handled outside of neutron or inside when routed-networks will be
supported.
This change makes the DHCP scheduler network reachability aware by
querying plugin's filter_hosts_with_network_access method.
This change provides an implementation for ML2 plugin delegating host
filtering to its mechanism drivers: it aggregates the filtering done by
each mechanism or disables filtering if any mechanism doesn't overload
default mechanism implementation[1] (for backward compatibility with
out-of-tree mechanisms). Every in-tree mechanism overloads the default
implementation: OVS/LB/SRIOV mechanisms use their agent mapping to filter
hosts, l2pop/test/logger ones return empty set (they provide to "L2
capability").
This change provides a default implementation[2] for other plugins
filtering nothing (for backward compatibility), they can overload it to
provide their own implementation.
Such host filtering has some limitations if a dhcp-agent is on a host
handled by multiple l2 mechanisms with one mechanism claiming network
reachability but not the one handling dhcp-agent ports. Indeed the
host is able to reach the network but not dhcp-agent ports! Such
limitation will be handled in a follow-up change using host+vif_type
filtering.

The functional test for auto_schedule_networks passes even if the
method does nothing. This patch changes the test so it checks that
each expected hosted network is in hosted_net_ids.

Non-obvious changes:
* Change helpers.register_agent to use a slimmed down version
of a plugin that knows how to register an agent. This allows
the helper to be used with tests that do not register a core
plugin.

In this blueprint, we also propose to write a generic scheduler
framework which can be used to schedule a new resource on
selected least loaded agents.
Currently dhcp_load_type will be fetched from neutron.conf file
and corresponding load is obtained by the agent report state.
The obtained load will be populated in the "load" column of the
agents table.
During scheduling, agent will be selected based on sorting all
the agents of particular type based on load column.
Example dhcp_load_type is networks
