add BaseV2ComputeTest as the base class of nova v2 api tests

this does refactor in compute.base, add BaseV2ComputeTest as
the base class of nova v2 api test. Because there will be nova
v3 tests, this change will be convenient to add BaseV3ComputeTest
as the base class of nova v3 api tests. In this way, we can split
v2 tests with v3 tests easily, and share some common method.

Partially implements blueprint nova-v3-api-tests

Forced isolation for the nova quota test

Several test cases like quota related tests should not be done without
creating a new tenant in all cases.

This change enforces the isolated code path for the nova quota tests.
These tests requires admin rights anyway, so probably no one want to
try to run them without admin permissions.

Use isolation credentials for neutron api tests

This commit just adds the use of isolated credentials to the neutron
api tests if tenant isolation is enabled. Previously the neutron
tests would all run in the same tenant regardless of the config
option.
