support nfs-mounted & existing sandboxes

[Doug Hellmann]

I am having a problem running with an NFS-mounted installation target directory. I get an error when the horizon installer tries to chown a file to root, because of the way vagrant sets up the NFS mount. This issue is related to another problem I have in which I want to reuse an existing git repository (so I can rebuild a VM containing OpenStack or install from my branch that I have checked out already, instead of cloning a new repository).

It seems like both issues can be solved by adding a new command line option to stack to let the developer separate the "installation" directory from the "source code" directory. The default location for source code could still be within the installation directory.

Here's the error I get:
