AttributeError: No such RPC function 'report_state'

This patch changes dhcp_agent_manager to be DhcpAgent instead of
DhcpAgentWithStateReport since not all plugins support DhcpAgentWithStateReport
and having this as the default breaks all current deployments that upgrade
source without changing their config files.

This code is no longer needed since nova can now proxy these calls to
quantum directly.

refactor LoadBalancerPluginDbTestCase setUp()

fixes bug: 1129417

This fixes the bug by changing LoadBalancerPluginDbTestCase to inherit
from test_db_plugin.QuantumDbPluginV2TestCase.  This allows for the
plugin to access context managers for core resources.  Additionally,
this change adds subresource and service_plugin support to
QuantumDbPluginV2TestCase.
