title: Refactor class method to property using Pycharm
body: <p>I have the following class:</p>
  
  <pre><code>class Dogs(object):
      def __init__(self):
          self.names = []
          self.breeds = set()
  
      def number(self):
          return len(self.names)
  </code></pre>
  
  <p>I want to change <code>number</code> to being a property. This means I also want to change all of it usages. Does PyCharm have this built into it's refactoring tools? It seems to be according to <a href="https://youtrack.jetbrains.com/issue/PY-17341" rel="noreferrer">this issue</a>.</p>
  
  <p>At this point, I'm doing "find all usages" and then manually fixing each instance. If there isn't a specific refactoring tool for changing a method to a property, is there some way to use "find all usages" more effectively?</p>
