[Rails52] Fix RollupRadarMixin deprecation warning
[Rails52] Fix RollupRadarMixin deprecation warning

The following gets printed at the top of specs:

    DEPRECATION WARNING: Leaving `ActiveRecord::ConnectionAdapters::SQLite3Adapter.represent_boolean_as_integer`
    set to false is deprecated. SQLite databases have used 't' and 'f' to serialize
    boolean values and must have old data converted to 1 and 0 (its native boolean
    serialization) before setting this flag to true. Conversion can be accomplished
    by setting up a rake task which runs

      ExampleModel.where("boolean_column = 't'").update_all(boolean_column: 1)
      ExampleModel.where("boolean_column = 'f'").update_all(boolean_column: 0)

    for all models and all boolean columns, after which the flag must be set to
    true by adding the following to your application.rb file:

      Rails.application.config.active_record.sqlite3.represent_boolean_as_integer = true
     (called from <class:MaxByLabel> at /Users/nicklamuro/code/redhat/manageiq/tools/radar/rollup_radar_mixin.rb:16)

So adding this fixes that.

Note:  Since this is a tool, most likely it will be used in "production" as
well and evaluated in "development", so that is another reason why this
was added to the `config/application.rb` (not just because the warning
told us to put it there...)
