/**
* The relationship policy determines how and where relationships between identities are stored.
*
* There is a one-to-one relationship between an IdentityConfiguration and RelationshipPolicy, i.e. each
* IdentityConfiguration has its own RelationshipPolicy.
*
* The RelationshipPolicy defines the relationship types that are managed by the IdentityConfiguration itself for
* "self-contained" relationships, i.e. relationships for which all participating identities belong to a partition
* governed by that IdentityConfiguration. It also defines the "global" (i.e. relationships between identities
* belonging to different partitions/configurations) relationship types that the IdentityConfiguration
* is capable of supporting.
*
* It is the responsibility of the developer to ensure that multiple RelationshipPolicy configurations do not provide
* overlapping support for the same global relationship types. If multiple IdentityConfiguration instances have been
* configured and their relationship policies provide overlapping support, the behaviour is undefined.
