title: Rubocop indentation configuration
body: <p>I would like rubocop to always only indent once. Also else, elsif and end shouldn't be indented at all. So something like this:</p>
  
  <pre><code>@shop = api
          .shop('de')['storefronts']
          .find_all do |front|
            front['name'] == 'WeeklyStorefront' ||
              front['name'] == 'DailyStorefront'
          end
          .map { |front|  font['catalogEntries'] }
          .flatten
          .map { |item| item['devName'] }
  </code></pre>
  
  <p>should look like this:</p>
  
  <pre><code>@shop = api
    .shop('de')['storefronts']
    .find_all do |front|
      front['name'] == 'WeeklyStorefront' ||
        front['name'] == 'DailyStorefront'
    end
    .map { |front|  font['catalogEntries'] }
    .flatten
    .map { |item| item['devName'] }
  </code></pre>
  
  <p>and this:</p>
  
  <pre><code>mode = if key.include? '_p2'
           'Solo'
         elsif key.include? '_p10'
           'Duo'
         else
           'Squad'
         end
  </code></pre>
  
  <p>should look like this:</p>
  
  <pre><code>mode = if key.include? '_p2'
    'Solo'
  elsif key.include? '_p10'
    'Duo'
  else
    'Squad'
  end
  </code></pre>
  
  <p>I tried a lot of different config options but I never got it to work properly.</p>
  
  <p>I tried:</p>
  
  <pre><code>Layout/MultilineMethodCallIndentation:
    EnforcedStyle: indented
  </code></pre>
  
  <p>that produces:</p>
  
  <pre><code>@shop = api
    .shop('de')['storefronts']
    .find_all do |front|
            front['name'] == 'WeeklyStorefront' ||
              front['name'] == 'DailyStorefront'
          end
    .map { |front| front['catalogEntries'] }
    .flatten
    .map { |item| item['devName'] }
  </code></pre>
  
  <p>and </p>
  
  <pre><code>mode = if key.include? '_p2'
               'Solo'
             elsif key.include? '_p10'
               'Duo'
             else
               'Squad'
  end
  </code></pre>
  
  <p>which is better but still not what i wanted.</p>
