sync periodic_task fix from incubator

Set the value of time the periodic task was last run to a multiple of the
spacing value rather than the actual last time run. This ensures tasks runs
regularly but avoids synchronizing that interval with other nodes.

This patch also removes the coalescing of tasks which are _nearby_ (0.2
seconds away).

NSX: remove unnecessary checks on network delete

Since commit b50e66f router interfaces are not deleted
automatically when the network hosting them is deleted.

The NSX plugin still has additional logic to ensure all the
corresponding backend resources have been deleted as well.
Such logic is now obsolete and can be removed. Moreover it
also wasteful as it perform queries for retrieving NSX
resource identifiers.

This patch also amends a few related log statement to make
them clearer.

Allow unsharing a network used as gateway/floatingip

If network has ports that connect it as gateway to another network, such
as an external network, or "floating ip" ports it should still be
possible to "unshare" it since these ports represent usage of the
network as an external network, not as a VM data network.

Clear entries in Cisco N1KV specific tables on rollback

During rollback operations, resources are cleaned up from neutron
database but leaves a few stale entries in the n1kv specific tables.
This change addresses the proper clean up of tables. i.e. VLAN/VXLAN
allocation tables, profile binding and vm network table.

Cisco: Fix test cases which make incorrect create requests

update vsm credential correctly

Today if we modify the n1kv VSM credential in the cisco_plugins.ini, the
older VSM ip address remains in the db, and all requests are sent to
the older VSM. This patch deletes all n1kv VSM credentials on neutron
start up before adding the newer VSM credentials. Hence making sure
that there is only one n1kv VSM IP address and credential in the db.

Log methods using rpc communcation

In Icehouse was used rpc library from oslo-incubator. Because the code

oslo.messaging we don't need to have debug level in oslo.messaging but

VPNaaS: Separate validation for Cisco impl

Moving validation logic from Cisco service driver, into a
validation subclass, so that it'll be applied during the
persistence phase (so validation failures can block the
persistence, instead of setting to error state).

This is part of the effort to separate out L3 validation
and builds upon the reference implementation changes being
reviewed in 102351.

Note: One unit test is commented out, due to a bug in
oslo.messaging 1.3.0. It will be uncommented later, once
1.4.0.0.a3 or newer is available for use.

Return a tuple of None's instead of one None

The expected return value of _commit_port_binding is something that
can be unpacked into two values. This changes the condition where a
concurrent delete was detected to return a 2-tuple of None's
instead of a bare None to prevent an iterable error.

Fix enums usage for postgres in migrations

For downgrade with postgres it is not enough to just drop_table if
table contains enums. The enums should be removed separately after
deleting the table.

Also, if a migration uses an existing enum then postgresql needs some
specific code to re-use this enum.

Fixed audit notifications for dhcp-agent-network

dhcp-agent-network-add and dhcp-agent-network-remove do not
generate audit notifications which are used for security
compliance.
CRUD operations of core network resources are handled by
neutron/api/v2/base.py. In base.py, each of create(), update(),
delete() methods makes calls to oslo.messaging.Notifier.info()
to generate these notifications.
In the proposed fix, it is fixed in a similar fashion in
extensions/dhcpagentscheduler.py inside create() and delete()
methods by introducing info() method calls inside them.

call security_groups_member_updated in port_update

When a running VM is added to a security group, all existing VMs (ports)
in the security group should be notified/updated - otherwise they would
have incorrect rules, not knowing the new VM/port added.

The current behavior would only update the port of the added VM. This
patch forces an security_groups_member_updated() call for all the
security groups that have ports removed or added.
