Refactor utils using installer adapters

JIRA: SFC-65
JIRA: SFC-71

Use the new library in releng to talk to fuel.
This allows for correct configuration of the compute hosts to resolve
SFC-71

Also since https://gerrit.opnfv.org/gerrit/#/c/28281/ was merged it
allows to run in multienv deployments so it resolves SFC-65
