Currently, there is no dns servers prioritization for subnets
for Neutron.
Generally speaking, it is useful to keep the order of dns
nameservers consistent. Add a new column named 'order' in table
'dnsnameservers' and add nameserver into DB one by one.

Commit 3e0328b992 broke external
decomposed plugins due to the fact that it assumes that the
context is set.
This patch validates that the context is set.

This patch implements the database model required for the network
RBAC work. In addition it migrates the current network and subnet
'shared' attributes to leverage the new table.
'shared' is no longer a property of the DB model because its status
is based on the tenant ID of the API caller. From an API perspective
this is the same (tenants will see networks as 'shared=True' if the
network is shared with them). However, internal callers (e.g. plugins,
drivers, services) will not be able to check for the 'shared' attribute
on network and subnet db objects any more.
This patch just achieves parity with the current shared behavior so it
doesn't add the ability to manipulate the RBAC entries directly. The
RBAC API is in the following patch.

Changed inheritance chain for NeutronDbPluginV2 to allow switching from
non-pluggable to pluggable IPAM implementation.
IpamNonPluggableBackend methods are called on it's instance,
instead of previous way where IpamNonPluggableBackend was parent for
NeutronDbPluginV2.
It allows switching IPAM implementation in set_ipam_backend
(IpamNonPluggableBackend to IpamPluggableBackend).
All methods that became public in IpamNonPluggableBackend were renamed.
This is refactoring step before Pluggable IPAM can be applied.

To keep pluggable and non-pluggable ipam implementation consistent
non-pluggable one has to be switched to track allocation_pools and
gateway_ip using SubnetRequests.
SubnetRequest requires allocation_pools to be list of IPRanges.
Previously allocation_pools were tracked as list of dicts.
So allocation_pools generating and validating was moved before
SubnetRequest is created.

Previously create_subnet called different methods for subnet allocation
with subnetpool and without it.
_create_subnet_from_implicit_pool and _create_subnet_from_pool
were collapsed into single method _create_subnet.
This is intermediate step for supporting pluggable ipam.

This reverts commit 1d61c5f736,
which reverted ee51ef72d3 due
to an issue with the allocation pools being mis-aligned with
the last address of a v6 subnet.
IPv6 does not have a subnet broadcast address so the last IP
address can be used as a regular address. This patch tweaks the
automatic allocation pool generation to include that last address
on v6 networks.
This was found because
NetworksTestDHCPv6.test_dhcp_stateful_fixedips_outrange makes the
assumption that the default generated pools cover the entire usable
address space.

This commit is a preparation step for using pluggable IPAM.
1. Moved get_subnets functionality to db_base_plugin_common to make it
accessible by ipam backends.
2. Reworked update_subnet routine:
- moved db part into update_db_subnet;

This commit is a preparation step for using pluggable IPAM.
- moved validations into _validate_port_for_update;
- updating ip addresses for port is backend specific, so
moved into _update_port_with_ips in ipam_non_pluggable_backend;
- writing port changes to db is common for both backends, so
moved into _update_db_port in ipam_backend_mixin;
- updated to use namedtuple to track add/original/remove ips;
- added _make_fixed_ip_dict to exclude keys other than
ip_address and subnet_id;

Moved private getters and simple helpers into db_base_plugin_common.
This change is part of bigger refactoring for supporting Pluggable IPAM.
Main purpose is to make getters accessible by IPAM code.
