allow_new_users setting

[jakobkukla]

With the python2 syncserver implementation it was possible to disable new user requests as seen below.

[syncserver]
...other settings...
allow_new_users = false

Is there an equivalent setting in syncstorage-rs? I couldn't find anything fitting while looking through the code but it is possible I missed it.

Thanks!

No, I don't believe that this is available in the rust version.
