Param jenkins jobs

Update jenkins job's configurations

There are two new parameter to configure at the job builder to manage properties which once were manually updated: * oneview-credentials-file * hwinfo-properties-file 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).

New configuration for for: * l3 plugin (jenkins vms lost connection through floating ip during stack) - https://review.openstack.org/#/c/356026/ * select images for testing (it was trying to use cirros instead)- https://review.openstack.org/#/c/329625/ * IPA download branch - recovered from jenkins edit history (last successful build in august) * unprovision_timeout - recovered from jenkins edit history (last successful build in august)
