Ember Validations deprecations

[jkleinsc]

One of the current deprecation errors in our code is caused by deprecated code in Ember Validations:
"Ember.keys is deprecated in favor of Object.keys" - this error message is coming out of the numericality validator in cases where we define a numericality with an operator. For example:

numericality: {
  greaterThan: 0,
}

In addition, given the list of blockers here, we may have some issues using Ember Validations in Ember 2.x: https://github.com/dockyard/ember-validations/labels/2.0-blocker

Everything seems to be working correctly in Ember 2.2.
