title: atlassian_python_api checking if blogpost exist
body: <p>I'm using atlassian-pytho-api version 3.4.1.
  I need to create a blogpost which I successfully made this way</p>
  <pre><code>confluence.create_page(space, title, content, type=&quot;blogpost&quot;)
  </code></pre>
  <p>Now, I want to update this blogpost under certain conditions, for that i need to check if the post exists or not. I tried using</p>
  <pre><code>confluence.page_exists(space, title)
  </code></pre>
  <p>But it just searches in PAGES not in the blogpost and hence couldn't find the post and I can't update. Is there any way to restrict page_exists to search in blogpost instead of pages ?</p>
