Beaker 2.0 to deprecate support for Ruby 1.8

[Alice Nodelman]

The merge of beaker PR 536 (https://github.com/puppetlabs/beaker/pull/536) will end beaker's support of Ruby 1.8.  The change will be effective with the planned release of beaker 2.0 in the next two weeks.

For most beaker users this will have no effect on their daily workflow.  For those who have dependencies that rely upon Ruby 1.8 you will want to first pin to beaker 1.x and then repair/upgrade the gems in question as the 1.x beaker line will not be maintained.

For beaker-rspec users the deprecation will take effect in the next month under beaker-rspec 3.0.  Again, pin to beaker-rspec 2.x line if you are currently unable to drop Ruby 1.8 in your workflow.

Thanks!
