title: InvalidDocument: key must not contain '.' and insert_one()
body: <p>Hey I have a json from <a href="https://github.com/GoogleChrome/lighthouse" rel="nofollow noreferrer">https://github.com/GoogleChrome/lighthouse</a> which i want to store with pymongo to a mongodb. There are some keys with dots, thus i get these errors: </p>
  
  <p>InvalidDocument: key '74245.20' must not contain '.'</p>
  
  <p>with just insert there was a check_keys=False option. Is there anything similar with insert_one? </p>
