Alignment rules missing for rescue/ensure

[lumeet]

Currently there seems to be no cop to complain about the following.

begin
  a
      rescue
        b
            ensure
              c
end

And if we start with:

begin
a
rescue
b
ensure
c
end

...and auto-correct, Style/IndentationWidth (alone) makes it to look like this (by default):

begin
  a
  rescue
    b
  ensure
    c
end

PRs welcome! :-)

Ok, I'll try to submit one soon as I happened to do some groundwork already. :) I guess it could be a new Lint cop that aligns the rescue and ensure keywords with the corresponding end without introducing any configs. EndAlignment and DefEndAlignment already do pretty good job to get that end aligned correctly. @bbatsov, @jonas054 Any comments at this point?

Sounds like a plan to me. I've nothing further to add at this point.
