TestHBCKCommandLineParsing#testCommandWithOptions hangs on call to HBCK2#checkHBCKSupport

      Description

      I noticed the following when running TestHBCKCommandLineParsing#testCommandWithOptions :

      "main" #1 prio=5 os_prio=31 tid=0x00007f851c800000 nid=0x1703 waiting on condition [0x0000700000216000]

      	at org.apache.hbase.TestHBCKCommandLineParsing.testCommandWithOptions(TestHBCKCommandLineParsing.java:62)
      

      The test doesn't spin up hbase cluster.
      Hence the call to check hbck support hangs.

      In HBCK2#run, we can refactor the code such that argument parsing is done prior to calling HBCK2#checkHBCKSupport .
