Fix staging_directory default path
Fix chroot builder to work with chef-solo

According to be5adb92b5c4d5d95e5089be94c706b930fea7ba, the UploadDir
method supports two ways of copying depending on whether a trailing
slash is used:
    src = "dir"  -> dest/dir
    src = "dir/" -> dest

On BSD-based systems (such as OSX, FreeBSD, etc.) the `cp -R` command
handles these two cases automatically.  However, Linux treats "src/" and
"src" the same.

To support the trailing slash syntax portably, we can use:
    src = "dir"   -> dest/dir
    src = "dir/." -> dest

This works on BSD and Linux.  It is better than using wildcards as it
grabs hidden files as well.

This fixes #1196 that prevents the chef-solo provisioner from working
with the chroot builder.

Force IPv4 addresses from address pools in Openstack. Fixes #1258

Rackspace defaults to a public IPv4 and IPv6 address. These are returned in
random order, with the sprintf further on generating an incorrect connection
string if on IPv6. Force IPv4 until support for correct connection strings and
a configuration flag for logging in over IPv6 is added.
Add ability to configure networks for openstack

Add configuration option `networks`, a list of network UUIDs, to attach to the
source instance.

In some openstack installs, no default network will be attached or the network
with the ability to attach a public floating IP will need to be specified.
