[tools] ksck improvements [3/n]: master consensus checks

This patch adds consensus consistency checks and a consensus matrix
for the master tablet. It's a little trickier than for tablets,
because there's no uuid available for an unavailable master.

Here's a sample matrix when a master is down:
WARNING: masters have consensus conflicts  All reported masters are:
  A = c9afe67944784c70ab13989354c10f9e
  B = <unknown uuid> (localhost:7052)
  C = 488cf2ab551b422aa8c683a054cdcde3
  D = 62dc9b532b084a459130f1676d8e1998
