Moved sample network creation out of unittest base class constructor.

This sample networks only needed in:

 nova.tests.api.ec2.test_cloud
 nova.tests.integrated.test_api_samples
 nova.tests.network.test_manager
 nova.tests.test_libvirt
 nova.tests.test_xenapi

Moreover, base class constructor is not good place for sample
data creation. Database should be empty before runing tests.

Fixes: bug 1181502

Adds ability to black/whitelist v3 API extensions

Adds a config option which will blacklist specific v3 API extensions
from being loaded even if they are detected.

Adds a config option which if the list is not empty will stop
any v3 API extension from being loaded unless it is in the whitelist.
No filtering occurs if the whitelist is empty

Creates a config option group osapi_v3 to hold the two new options
and osapi_v3_enabled renamed to just enabled within the new group

Partially implements blueprint v3-api-extension-framework
