Display the nodes summary once the cluster is established using
redis-trib.rb
After the cluster meet and join was done, when the summary was shown, it
was giving info regarding the nodes. This fix ensures that confusion
where the slaves were shown as masters.
Fix would be to reset the nodes and reload the cluster information
before checking the cluster status after creating it.

This commit changes what provided by PR #3315 (merged) in order to
let the user specify the log level as a string.
The define could be also used, but when this happens, they must be
decoupled from the defines in the Redis core, like in the other part of
the Redis modules implementations, so that a switch statement (or a
function) remaps between the two, otherwise we are no longer free to
change the internal Redis defines.

Most of the time to check the last element is the way to go, however
there are patterns where the contrary is the best choice. Zig-zag
scanning implemented in this commmit always checks the obvious element
first (the last added -- think at a loop where the last element
allocated gets freed again and again), and continues checking one
element in the head and one in the tail.
Thanks to @dvisrky that fixed the original implementation of the
function and proposed zig zag scanning.

This bug most experienced effect was an inability of Redis to
reconfigure back old masters to slaves after they are reachable again
after a failover. This was due to failing to reset the count of the
pending commands properly, so the master appeared fovever down.
Was introduced in Redis 3.2 new Sentinel connection sharing feature
which is a lot more complex than the 3.0 code, but more scalable.
Many thanks to people reporting the issue, and especially to
@sskorgal for investigating the issue in depth.
Hopefully closes#3285.
