Remove static NS resolution from seed image

Seed VM is getting NS resolution from its DHCP lease given by libvirt. There is no need for manually specifying resolv.conf.
Besides, these two files were having bad filenames (.conf suffix) preventing them to by executed by dib-run-parts script
(see dib-run-parts regex : allowed_regex=${RUN_PARTS_REGEX:-"^[0-9A-Za-z_-]+$"} )

Upgrade setuptools to 1.10 or more in a newly created virtualenv

By default, virtualenv embeds setuptools, and doesn't download its
latest version. At the moment, latest virtualenv is 1.10.1, which does
install setuptools-0.9.8

Unfortunately, setuptools-0.9.8 doesn't manage correctly HTTPS
certificates if the user is specifying a proxy with https_proxy and
http_proxy environments variables. This can raise an error if the
server to download is having TLS2_3 HTTPS certificate, by example when
pip installing python-novaclient, whick asks for
https://pypi.python.org/simple/pbr

Fixes: bug #1201253

Add Ironic database creation to boot-stack

This patch will add creation and db-sync of Ironic database if Ironic
environment is found. This will allow developers to include the Ironic
element in the under-cloud image and deploy it from the seed vm for
development work and integration testing.

Remove orc/oac from heat-cfntools dependency chain

With os-collect-config, we no longer use cfn-hup to run
os-refresh-config. Without that need, we no longer need os-apply-config to
configure cfn-hup.

Add os-apply-config to os-collect-config deps

This was an oversight because os-collect-config was being pulled in most
of the time with os-apply-config. However, any element that uses o-a-c
templates should definitely directly depend on o-a-c.
