New configuration for for:
* l3 plugin - https://review.openstack.org/#/c/356026/
* select images for testing - https://review.openstack.org/#/c/329625/
* IPA download branch - recovered from jenkins edit history
* unprovision_timeout - recovered from jenkins edit history

There are two new parameter to configure at the job builder:
* oneview-credentials-file
* hwinfo-properties-file
These files hold the properties that once were manually applied at
Jenkins configuration dashboard. This is possible due to Jenkins'
'copy-to-slave' and 'envinject' plugins. This patch also disables
DNSSEC check made by 'unbound' at slaves (could not resolve *.org
names using LSD new DNS server).

Update DNS config at nodepool.yaml

Atualiza configurações de DNS carregadas pelo nodepool

The oneview-integration-tests repo was moved from Thiago's project to under
IronicDrivers project umbrella on gitlab. This patch changes the download link
for the jjb script for power & management job.

Sometimes, nodepool was creating 2 nodes with iscsi label. This should
workaround that.
