NSX: allow multiple networks with same vlan on different phy_net
Previously, the NSX plugin prevented one from creating multiple networks on
the same vlan even if they were being created on different physical_networks.
This patch corrects this issue and allows this to now occur.

Big Switch: Don't clear hash before sync
This patch removes the step of clearing the consistency
hash from the DB before a topology sync. This will ensure
that inconsistency will be detected if the topology sync
fails.
This logic was originally there to make sure the hash header
was not present on the topology sync call to the backend.
However, the hash header is ignored by the backend in a sync
call so it wasn't necessary.

Use EUI64 for IPv6 SLAAC when subnet is specified

Disable PUT for IPv6 subnet attributes
In Juno we are not ready for allowing the IPv6 attributes on a subnet
to be updated after the subnet is created, because:
- The implementation for supporting updates is incomplete.
- Perceived lack of usefulness, no good use cases known yet.
- Allowing updates causes more complexity in the code.
- Have not tested that radvd, dhcp, etc. behave OK after update.
Therefore, for now, we set 'allow_put' to False for the two IPv6
attributes, ipv6_ra_mode and ipv6_address_mode. This prevents the
modes from being updated via the PUT:subnets API.

ML2: move L3 cleanup out of network transaction
Move _process_l3_delete out of the delete_network
transaction to eliminate the semaphore deadlock that
occurs when it tries to delete the ports associated
with existing floating IPs.
It makes more sense to live outside of the transaction
anyway because the operations it performs cannot be
rolled back only in the database if the L3 plugin makes
external calls for floating IP creation/deletion.
e.g. if delete_floatingip is successful, it may have
deleted external resources and restoring the DB records
would make things inconsistent.
If a failure to delete the network does occur, any cleanup
done by _process_l3_delete will not be reversed.

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

The problem was introduced by commit acf44dba26ca8dca47bfb5fb2916807f9f4e2060
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.
Neutron cannot possibly be passing tests under Python 2.6, as
neutron/tests/unit/test_api_v2.py is referencing
