NSX: Fix status sync with correct mappings

The code that syncs router status to the neutron_db was using the nsx
router id instead of the neutron router id thus synchronize_router
would never update the database.

Also, the switch synchronization routine was not fetching the
appropriate neutron id tag thus causing switch synchronization to
be skipped.

This patch also fixes the error in the unit tests which allowed for
the bug to be introduced.

Lower log level of errors due to user requests to INFO

Errors due to bad client requests (e.g., NotFound, BadRequest)
are logged as exception/trace level and it is annoying
from the point of operators' view.
This commit changes the log level for errors due to
user requests (HTTP 4xx errors) to INFO.

Rename DB models and related resources for VMware NSX plugin

This patch also introduces a DB migration to update the
affected tables, and the enum type for those DB engines that
require it.

Additions made to existing migrations are needed to ensure
that green deployments using the new plugin name will apply
the migrations correctly.

NSX: Fix newly created port's status should be DOWN

Previously when creating a port in neutron using the nsx plugin
the port status returned would be ACTIVE even if this was not the
case. Now, DOWN is returned which will be updated by the backend
when the port goes ACTIVE.
