Typographical correction of Arista ML2 help

The Configuration Reference Guide on docs.openstack.org contains
configuration tables generated based on the help strings defined
in the Python code.

Typographical errors in the source for the Arista ML2 plugin,
particularly a lack of spaces between the start and end of
continuing lines, were resulting in errors in the guide.

Properly apply column default in migration pool_monitor_status

server_default parameter should be used to apply default value at
table/column creation time. Otherwise non-nullable column can't
be created because of existing rows in the tables.

Make default nova_url use a version

The default nova_url for neutron is missing an API
version number. This can cause requests to fail
because the Nova /versions API cannot respond
to Neutron notification requests.

It seems reasonable for the default value to
at least have a chance at being correct so
this patch upgrades the default Nova API url to
use the Nova 'v2' API.

Verify ML2 type driver exists before calling del

Verifies that an ML2 type driver exists for a given
segment type before attempting to call the release_segment
method on it. Logs an error if a type driver is not
found.

This covers the case where a segment is created with
a given type and then ML2 is reconfigured without
support for that type.

DocImpact
The ML2 documentation should be updated with a warning
that disabling a network type driver and re-enabling
it later may lead to possible DB inconsistencies.

Add nova_api_insecure flag to neutron

Neutron did not have any way to allow SSL validation problems in the
novaclient similar to the way nova has the neutron_api_insecure flag.
This change adds the nova_api_insecure flag to the neutron config and
also passes it in the novaclient instantiation.
