Add a --text-out option to salt for "pretty printing" cmd.run output
Add a --text-out option to salt for "pretty printing" cmd.run output

This is *heavily* inspired from onall:
https://code.ticketmaster.com/trac/browser/onall/trunk/onall?format=txt

Example onall output:
$ echo ops{1,2}.els{0,2}2.int | onall -qy hostname
ops1.els2.int: ops1.els2.int
ops1.els0.int: ops1.els0.int
ops2.els2.int: ops2.els2.int
ops2.els0.int: ops2.els0.int

$ echo ops{1,2}.els{0,2}2.int | onall -qy date
ops1.els2.int: Thu Jul  7 01:08:04 EDT 2011
ops1.els0.int: Thu Jul  7 01:08:04 EDT 2011
ops2.els2.int: Thu Jul  7 01:08:04 EDT 2011
ops2.els0.int: Thu Jul  7 01:08:04 EDT 2011
