guest: import cloud-init from meta-openstack

Bringing cloud-init from meta-openstack into meta-virtualization to make
it more visible/obvious for use with Xen and k*s images.

Not only is this an import, it is a significant update to the package
and the way it is built.

Out of the box, it installs either systemd or sysvinit startup services,
templates and the main script/binary.

It is not expected that this will be useful out of the box, but will
need to be bbappended and have variables added to the main recipe to
make it flexible for more use cases.

But we can't gather those use cases, without the package being
available, so we integrate this as a starting point.

+Subject: [PATCH] setup.py: check for 'install' anywhere in args
+
+The python3distutils bbclass calls setup.py in a different way then
+cloud-init expects .. the 'install' is not argument 1, but is in fact
+after a 'build' and some other options.
+
+So rather than checking for install to be argv[1], we check for it
+anywhere in the arguments are trigger the template replacement to
+happen.
