overlay is missing profile/ and metadata/ directories

[ckonstanski]

Layman overlays are supposed to have a couple directories that are missing from the openstack overlay.

An example from the emacs overlay:

root@sphinkpad:/var/lib/layman/emacs # tree profiles/
profiles/
├── categories
└── repo_name

root@sphinkpad:/var/lib/layman/emacs # tree metadata/
metadata/
└── layout.conf

Here are the warnings I get when trying to use the overlay:

root@sphinkpad:~ # emerge -s python-designateclient
!!! Repository 'openstack' is missing masters attribute in '/var/lib/layman/openstack/metadata/layout.conf'
!!! Set 'masters = gentoo' in this file for future compatibility
WARNING: One or more repositories have missing repo_name entries:
/var/lib/layman/openstack/profiles/repo_name
NOTE: Each repo_name entry should be a plain text file containing a
unique name for the repository on the first line.

My portage version is: sys-apps/portage-2.2.26:0
