Idmapper: Limit max group-cache entries, and add a fifo queue This change limits the max number of group entries in the cache. The limit is configurable through the DIRECTORY_SERVICES section in Ganesha config. The cache eviction strategy is determined using the fifo queue. The fifo queue order mimics the order of expiration time of the cache entries, since expiration time is a linear function of the insertion time -- expiration_time = insertion_time + cache_validity (constant) The head of the queue therefore contains the entry with least time-validity, and the tail of the queue contains the entry with most time-validity. The eviction happens from the head, and insertion happens at the tail.
