Quality of QUIET log output

[dsetrakyan]

In continuation to my previous email about INFO level log output, we also
have a big problem with QUIET log mode. Here is an example of a single node
output after another node joined and left 3 times:

[22:50:23] Ignite node started OK (id=931fcf60)

We are printing out the same information over and over again. For example,
regions configuration does not change, why do we print it out every time?
The same goes for the node ID, it stays constant. Moreover, we should not
be printing out full node IDs in quite mode.

I suggest we fix it as follows:

   1. Print out data regions once on startup, right before we print out
   that *"Ignite node started OK (id=931fcf60)"*
   2. Remove *"^--Node [...]"* printout underneath topology snapshot
   altogether
   3. Rename "clusterState=ACTIVE" to "state=ACTIVE" and add it to the
   topology snapshot line.

I have filed a blocker ticket for 2.7 release:
