Should we add IdentityResolver implementation mentioned above by [~ntikhonov] to ignite-hibernate
module or\and update documentation to resolve this ticket?

> {{org.hibernate.cache.spi.CacheKey}} is a class used as a key for all entries in the
Hibernate L2 cache. This class contains {{type}} field and custom {{equals}} logic where the
type is used as a helper and does not participate in comparison. Instances of the same type
are producing different hash codes in different JVMs, which actually breaks comparison when
binary format is used, where byte arrays are compared.
