Latest dmtest setup needs ruby 2.2.2

[yizhanglinux]

Hello Joe

During setup dmtest with "gem update", got below error, seems it need to change to use Ruby 2.2.2
Gem::InstallError: activesupport requires Ruby version >= 2.2.2

After I use "rvm install 2.2.2", the setup succeed, and I execute below command and encountered below error:
# dmtest list --suite cache
/root/device-mapper-test-suite/lib/dmtest/suites/cache.rb:11:in `require': cannot load such file -- dmtest/tests/cache/latency_tests (LoadError)

#dmtest list --suite cache
superclass must be a Class (FalseClass given)
/root/device-mapper-test-suite/lib/dmtest/tests/cache/vdbench_tests.rb:16:in `<top (required)>'

#dmtest list --suite cache
/root/device-mapper-test-suite/lib/dmtest/suites/cache.rb:23:in `require': cannot load such file -- dmtest/tests/cache/warming_tests (LoadError)

Now have to annotate below three lines to test dm-cache
device-mapper-test-suite/lib/dmtest/suites/cache.rb

require 'dmtest/tests/cache/latency_tests'

require 'dmtest/tests/cache/vdbench_tests'

require 'dmtest/tests/cache/warming_tests'

Why do you think it needs Ruby version 2.2.2 ? .ruby_version states 1.9.3.
Are you having some trouble with gem dependencies? In which case the right
solution is to pin the gems in question.

The errors you see when running gem update are nothing to do with dmtest, I think that's the gem code itself, and you can safely rvm install ruby-2.2 to fix it.

The errors when running bundle update are hopefully fixed with this patch which pins some gems:

Could you try and confirm please?

Great. I'm in the process of updating to Ruby 2.3.1. But that should fix
things for the time being.
