Add unit tests covering single operations to ODL

This commit adds the remaining test cases (create and update
operations) to fully cover sync_single_resource. It also defines the
filter_* methods as static or class methods and removes their duplicate
arguments.

Rename workers to api_workers and simplify code

Refactor a few ugly aspects of the multiple API worker patch to make
way for multiple rpc workers.  This came up as I was trying to add
multiple RPC workers using similar patterns and remembering that some
things were left in a rather awkward state.

Fix to delete user and group association in Nuage Plugin

After a router delete operation, the attached zone to that
router is also deleted. Got rid of code that tried to do
a get operation on the nuage_zone after router delete
operation.

Eliminate OrderedDict from test_api_v2.py

Neutron cannot possibly be passing tests under Python 2.6, as
neutron/tests/unit/test_api_v2.py is referencing
collections.OrderedDict, which does not exist in Python 2.6.
Since there is no reason to use an OrderedDict in this case,
this replaces it with a simple dict.

Stop admin using other tenants unshared rules

If the firewall rules are not shared and if they belong to different
tenants, then admin should not be able to create a policy using
these rules and he should not be able to insert such rules into
policies. An exception should be raised in such case. Added new
exception “FirewallRuleConflict” to handle such conditions.

Security groups: prevent race for default security group creation

When a VM is booted via the Nova the client connection is created
with an admin user. This causes problems when creating the neutron
port. That is, there may be a race for the creation of the default
security group for the tenant.
The problem was introduced by commit acf44dba26ca8dca47bfb5fb2916807f9f4e2060

Do not assume order of body and tags elements

This fixes the l2gateway unit test that breaks with a randomized PYTHONHASHSEED
(see the bug report).

The test assumed that the body dict from self._create_expected_req_body
had elements (including contents of tags list) in a particular order.
Found with PYTHONHASHSEED=2455351445.
The fix ensures that body is in predictable order.

Partial-bug: #1348818
Note: There are several other unrelated unit tests that also break with a
randomized PYTHONHASHSEED, but they are not addressed here. They will be
addressed in separate patches.

Revert "Cleanup floatingips also on router delete"

This reverts commit c3326996e38cb67f8d4ba3dabd829dc6f327b666.

The patch being reverted here addresses an issue that can no longer be
reproduced, in that under no circumstances, I can make the FIP lie around
before deleting a router (which can only be done after all FIP have been
disassociated or released).

Unless we have more clarity as to what the initial commit was really meant
to fix, there is a strong case for reverting this patch at this point.

Fix broken port query in Extraroute test case

One of the queries in an extra route test case tries
to filter based on the port owner, but the _list_ports
method it calls doesn't take a device_owner parameter.
This can cause failures if a DHCP port is created on
the same subnet.
