Bug 1855088: generate unique role and binding names

When same permission rules are defined for different ServiceAccounts,
OLM would generate same name for (Cluster)Role and (Cluster)RoleBinding related to this rules.
This change should ensure that unique names are generated,
taking into account ServiceAccount name and CSV Name and
CSV namespace (for ClusterRole)
