-Very incomplete testing right now
-Puts the password and stackrc files in the current user's home
directory during the install. Given that they now have secure
permissions and we recommend doing that anyway, I think it's fine,
but it is a non-trivial change in behavior.
This was done because it's awkward to read a root-owned file from
a Python process running as a regular user.
-Uses oslo.config instead of the bash-style answers file. A sample
conf file created by the oslo.config generator is included (for
now, although we may want to generate that dynamically at some
point). Backwards compatibility with existing answers files is
maintained for now, but is deprecated.
-Hard-codes the image path in instack-test-overcloud to . It's
difficult to extract the value from the conf file in bash (unless
they overrode the default, there's nothing for ConfigParser to read),
and since it's just a simple sanity test script I think that's okay,
at least for now.
