Remove `:managed_config` option.

In practice, it was already removed half a year ago, but the description
 and cheatsheet entries were still there.

The migration intentionally does not use ConfigDB.get_by_params, since
this will break migration code as soon as we add a new field is added
 to ConfigDB.

Closes #2086

+switched to a new configuration mechanism, however it was not officially removed until now.
 
 ### Changed

 * `public`: Makes the client API in authenticated mode-only except for user-profiles. Useful for disabling the Local Timeline and The Whole Known Network. Note that there is a dependent setting restricting or allowing unauthenticated access to specific resources, see `restrict_unauthenticated` for more details.
 * `quarantined_instances`: List of ActivityPub instances where private (DMs, followers-only) activities will not be send.
