docs: unit tests doc links to hacking repo docs which isn't particularly helpful

[Matt Riedemann]

This page:

https://docs.openstack.org/nova/latest/contributor/testing.html#unit-tests

Links to:

https://docs.openstack.org/hacking/latest/user/hacking.html#creating-unit-tests

Which is specific to writing unit tests for the hacking repo, not nova. The nova docs should probably point at the nova hacking docs instead:

https://github.com/openstack/nova/blob/master/HACKING.rst#creating-unit-tests

    doc: fix link to creating unit tests in contributor guide

    The testing strategy doc was linking to the hacking repo docs
    on creating unit tests, which are very specific to creating
    unit tests for hacking rules.

    This changes the link to the 'creating unit tests' section in
    the HACKING.rst file, which has more information on testing
    within nova.

    Along with that change, the HACKING.rst testing section is
    updated a bit to point out that we use stestr now instead of
    testr and adds a proper link to the development environment
    quickstart docs.

    The nova/tests/unit/README.rst actually needs a lot of work,
    but that's left for another day.
