[add sim case]

tests/script/unique/arbitrator/dn2_mn1_cache_file_sync.sim

+# Test case describe: dnode1 is only mnode, dnode2/dnode3 are only vnode
+# step 1: start dnode1
+# step 2: start dnode2 and dnode3, and all added into cluster (Suppose dnode2 is master-vnode)
+# step 3: create db, table, insert data, and Falling disc into file (control only one file, e.g. 1841)
+# step 4: insert old data(now-15d) and new data(now+15d), control data rows  in order to save in cache, not falling disc 
+# step 5: stop dnode2, so date rows falling disc, generate two new files 1840, 1842 in dnode2
+# step 6: insert two data rows: now-16d, now+16d
+# step 7: restart dnode2, waiting sync end
+# expect: in dnode2, the files 1840 and 1842 will be removed
