Fix #1889 - Align fat arrows

[dgellow]

Fix PUP-1889.

Format resource's attributes according to the style guide, section
9.2 "Arrow Alignment".

Current behaviour

I have a resource Exec['test']. If I indent the code (with for exemple indent-region), nothing happen.

    exec { 'test':
      subscribe => File['/etc/test'],
      refreshonly => true, | ;; cursor is here
    }

Hit Tab, or select resource and call indent-region.
Nothing change.

New behaviour

Same resource, attributes are formatted with Tab, C-m, C-j,
indent-region, etc.

    exec { 'test':
      subscribe => File['/etc/test'],
      refreshonly => true, | ;; <- cursor is here
    }

Hit Tab. Attributes are formatted.

    exec { 'test':
      subscribe   => File['/etc/test'],
      refreshonly => true, | ;; <- cursor is here
    }
