Simplify delete_health_monitor() using cascades

Currently delete_health_monitor() emulates behaviour of
cascade deletion: when a HealthMonitor instance is deleted,
all corresponding PoolMonitorAssociations are queried and
deleted one by one. This can be done automatically by means
of SQLAlchemy if we set proper cascade flags on the relationship
between HealthMonitor and PoolMonitorAssociations models.

Fixes bug 1169107.

Create veth peer in namespace.

 * Update veth pair creation to set the namespace of the peer
   device on creation rather than subsequently adding it to the
   namespace.
 * This change supports kernels with limited namespace support
   (e.g. RHEL 6.5) so long as ovs_use_veth is set to True.
 * Addresses bug 1171727

Simplify NVP plugin configuration

Fixes bug #1121605

This patch replacest the nvp_controller_connection configuration option
with a set of options more intutitive to user which also avoid
repetitions in ini files.

In order to simplify the configuration of the plugin, this patch also
removes named clusters. As the plugin supports a single cluster at
the moment, this can be simply specified in the [DEFAULT] configuration
section.

Also, this patch restrucures nvp_cluster.NvpCluster so that per-cluster
configuration options are not store anymore multiple times.

Remove calls to policy.enforce from plugin and db logic

Blueprint make-authz-orthogonal

This patch implementes item #2 of the blueprint
Remove calls to policy.enforce when the policy check can be performed
safely at the API level, and modify policy.json to this aim.
This patch does not address enforce calls in the agent scheduler
extension, as that extension is currently not defined as a quantum.v2.api
resource class.
This patch also adds an API-level test case for the provider networks
extension, which was missing in Quantum and was necessary to validate
the API behaviour with the default policy settings.
