DATACMNS-630 - Integrate projection infrastructure from Spring Data REST.
Ported the projection infrastructure previously residing in Spring Data REST and extended it by defaulting to a Map-backed source to store and retrieve data. Separated out the SpEL based functionality mostly for SOC-reasons and easier testability. Related tickets: DATAREST-437, DATACMNS-618, DATACMNS-89.
