Clarifying fault propagation between phys-virtual
A fault affecting a physical resource my affect another physical or virtual resources. This fault correlation shall be configurable in VIM This patch is based on the related unresolved comment in https://gerrit.opnfv.org/gerrit/#/c/304 JIRA: DOCTOR-4 Signed-off-by: Balazs Gibizer <balazs.gibizer@ericsson.com> Change-Id: Ife1da03f31fc9d06bb5295157825760fc1139a36
