add support for QuerySet.select_related()

[Jibola]

Steps to reproduce

Successfully created a superuser. Once I created a superuser I attempted to work through the admin page. This then failed with the error QuerySet.select_related() is not supported.

<pre class="exception_value" style="padding: 0px; margin: 10px 0px; font-size: 1.5em; white-space: pre-wrap; word-break: break-word; font-family: sans-serif; color: rgb(87, 87, 87); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">QuerySet.select_related() is not supported on MongoDB.</pre>

We can't support selected related until we support joins. If we can't support joins (or until we can, if it'll be a longer-term goal), we may be able to ignore select_related().
