make neutron-ns-metadata-proxy configurable

Introduced a new configuration parameter for DHCP and L3 agent
to be able to set the path of the metadata socket to be used
by neutron-ns-metadata-proxy when started inside the DHCP or L3
agent. Also moved the configuration parameter of the
neutron-ns-metadata-proxy to the CLI parameters.

Fix ML2 VXLAN TypeDriver DB migration

The migration for the ML2 VXLAN TypeDriver was incorrectly setting
primary key attributes on separate lines for 'ip_address' and
'udp_port'. Also, a primary key cannot have autoincrement set, so
add this to 'udp_port' as well.

Syslog support for neutron metadata proxy

When neutron metadata proxy reads the cli args
which are propagated from its parent processes
(l3-agent and dhcp-agent), if log-dir and log-file
are not defined in the context, it will also
double-check whether syslog is enabled and
its facility in the user-defined configuration
files (/etc/neutron).
As a result, the log behavior of each neutron
component becomes consistent.
File log is the default logging function. The syslog
is enabled when use_syslog is explicitly defined and
file log options are all disabled.

Add ext-gw-mode support to ML2

Closes-Bug: #1212772

ML2 doesn't support ext-gw-mode, resulting in L3 agents not
setting-up NAT rules in neutron routers (currently, l3 agents
will assume enable_snat=false if plugin doesn't provide this
parameter as described in bug 1212868)

This patchset adds the support of ext-gw-mode to ML2 plugin.

In order to support ext-gw-mode alembic migration (as well as
other potential migrations on plugin dbs), folsom_initial
migration script is fixed to include ML2 plugin. Otherwise
databases won't be set-up during migration script (but at
plugin startup by sqlalchemy), resulting in migration failures.

Remove calls to policy.check and policy.enforce from plugin code

This patch removes a few explicit policy checks recently added to

They are not necessary as the same checks are already performed
