Description

RS dump information as follows

RS Queue:
===========================================================
Compaction/Split Queue summary: compaction_queue=(20:0), split_queue=0, merge_queue=0
Compaction/Split Queue dump:
  LargeCompation Queue:
    Request = regionName=usertable,user4180497275766179957,1491904095205.1d4085e4438752f3611f66e7b043fe44., storeName=0, fileCount=1, fileSize=1.9 G (1.9 G), priority=1, time=21697920409804647
    Request = regionName=usertable,user4568009753557153251,1491904099262.95bf004e3c9b35a58c60ca5d5b11d190., storeName=0, fileCount=1, fileSize=1.9 G (1.9 G), priority=1, time=21697920413223800
  SmallCompation Queue:
    Store = b, pri = 108
    Store = b, pri = 108
    Store = b, pri = 108
    Store = b, pri = 108
    Store = b, pri = 108
    Store = b, pri = 109

Compaction queue information will be displayed on page /dump.
If compation has selected the file, it will print the details information of the compation, otherwise only print storename and priority(Store = b, pri = 108) which is useless for us.
So, we should also print more detailed information, such as regionName, starttime etc.
