Add bpf_timer test that creates timers in preallocated and non-preallocated hash, in array and in lru maps. Let array timer expire once and then re-arm it for 35 seconds. Arm lru timer into the same callback. Then arm and re-arm hash timers 10 times each. At the last invocation of prealloc hash timer cancel the array timer. Force timer free via LRU eviction and direct bpf_map_delete_elem.
