debug-log should show relation settings changes

[Ahmed Kamal]

debug-log should show relation settings changes. These changes along with hook firing sequence are key to understanding what's really happening

[Kapil Thangavelu (hazmat)]

Something along the lines of the following?

  unit:mysql/0 hook.invoker flushed values for hook db-relation-changed
      added: username -> 'wordpress'
      added: password -> 'sadr13w0r98uo'
      modified: encoding 'wp1251' -> 'utf-8'
      deleted: timeout -> 12

I forgot to chime in here, but I am against this.

Do not write this to a log unless the formula author says its ok. This
data is still "sensitive" and writing it to a log file means it might get
rotated, saved, and examined later, versus having it only in zookeeper
and/or on the nodes while the data is in use.

Let formula authors decide what gets printed, please. I think just taking
the values out from the message below would be fine.. and listing which
values were changed.
