Revert "Skip test_list_server_addresses if neutron"

This reverts commit 3c7f98f0b78444e3cfc411a331d40ceb07629c21.

Since blueprint admin-event-callback-api in Icehouse we shouldn't
have this issue so enable the test again.

quota testcases use tenant_name should use tenant_id

Test case related to quota usage (test_show_quota_usage,
test_cinder_quota_defaults and test_cinder_quota_show)
uses tenant name, ideally it should use tenant id as quota
requires UUID of tenant and not tenant name.

Cinder quota-show ideally requires tenant_id to show quota.
As there is bug in cinder (BUG: 1307475) , that if we give
non-existent tenant_id still cinder show the quota and
returns 200 (OK). Hence, these testcases should use
tenant_id and not tenant_name.

Attempt to test live_migration by default

Now that we are starting to try testing multi node devstack we want to
test live_migration. In single node setups the live_migration tests will
be skipped  since the tests make sure there are at least two compute nodes first.

Ignore NotFound during network cleanup on API

Some resources are explicitly deleted by the test. When cleanup tries to delete
these resources, it should ignore NotFound exceptions thrown for resources that
were correctly deleted by the test.
