Function fbas_analyzer::find_symmetric_clusters

pub fn find_symmetric_clusters(fbas: &Fbas) -> Vec<QuorumSet>

Finds groups of nodes (represented as quorum sets) such that all members of the same group have (logically) the same quorum set and the common quorum set is comprised of exactly the group of nodes (a symmetric cluster). This function implicitly patches quorum sets so that each node is always included in its own quorum set. Getting a result with more than 1 entry implies that we don’t have quorum intersection.
