Add a gate-specific tox env for functional tests

The functional gate jobs (*-neutron-dsvm-functional) need special
configuration (e.g. OS_SUDO_TESTING, OS_ROOTWRAP_CMD) to run tests.
This patch adds a new gate-specific tox env (tox -e dsvm-functional)
that sets the appropriate values and allows easy duplication of the
results of the upstream job on a host that has successfully run
devstack with neutron enabled.

A new configuration option, OS_FAIL_ON_MISSING_DEPS, is also set by
the dsvm-functional tox env to ensure that dependency failures will
result in failures rather than skips when run in the gate.

Mock out tunnel_sync in test to avoid sleeping

The tunnel_sync call in the daemon loop for the ovs tunnel
tests blocks for 30 seconds. This patch mocks it out to stop
that.

Validate expected parameters in add/remove router interfaces

The add and remove router interface methods check that interface_info
is not empty but don't check if it contains any of expected parameters:
port_id and subnet_id
This patch adds a helper method to validate that interface_info contains
at least one of the expected parameters
Include a unit test for the empty port_id and subnet_id case

Dnsmasq config files syntax issue when dhcp_domain is empty

When using dhcp-agent with the following property dhcp_domain=""
addn_hosts and host files genererated for Dnsmasq have wrong syntax
concerning hostname parameter (dot char at the end).

As described in RFC-952 the hostname grammar is as follows:
<hname> ::= <name>*["."<name>]
<name>  ::= <let>[*[<let-or-digit-or-hyphen>]<let-or-digit>]
Hence it can't be conclude with a dot char.

Dnsmasq process is waiting for a hostname (2nd parameter) in the
following files:
"addn_hosts" file contains:
   20.0.0.3 host-20-0-0-3. host-20-0-0-3
"host" file contains:
   fa:16:3e:bf:e1:e4,host-20-0-0-3.,20.0.0.3

With the patch you will get:
"addn_hosts":
   20.0.0.3 host-20-0-0-3 host-20-0-0-3
"host":
   fa:16:3e:bf:e1:e4,host-20-0-0-3,20.0.0.3

Allow to import _LC, _LE, _LI and _LW functions directly

_LC, _LE, _LI, _LW are translation helper functions. This change updates
hacking rules to allow importing them directly:

    from neutron.openstack.common.gettextutils import _LC
    from neutron.openstack.common.gettextutils import _LE
    from neutron.openstack.common.gettextutils import _LI
    from neutron.openstack.common.gettextutils import _LW

neutron.policy module has been updated as an example of _LE, _LI and
_LW uses.

Fix DVR regression for ofagent

Background:
    ML2 plugin sometimes uses truncated port uuids.
    For example, in the case of ofagent and linuxbridge,
    if port id is 804ceaa1-0e3e-11e4-b537-08606e7f74e7,
    an agent would send "tap804ceaa1-0e" to the plugin.
    ML2 plugin's _device_to_port_id() would restore it to
    "804ceaa1-0e".  While it's still truncated, ML2 plugin's
    get_port() handles that by using "startswith".

The recently merged DVR change (https://review.openstack.org/#/c/102332/)
assumes that port_id is always a complete uuid (it's the case
for openvswitch) and fails to handle the above mentioned case.
This commit fixes the regression.

Add partial specs support in ML2 for vlan provider networks

ML2 provider networks partial specs let admins choose some provider
network attributes and let neutron choose remaining attributes. This
change provides the implementation for VLAN provider networks.

In practice, for VLAN provider networks provider:physical_network
and provider:segmentation_id choices can be delegated to neutron,
in such case neutron will try to find a network in tenant network
pools which respects provided provider attributes.
