`max-size` (quota) option

@aawsome I assume max-size is about request/response size or the files being transmitted? Could you clarify, didn't read much out of it from the Readme Todos.

I think this refers to the max-size option as implemented in rest-server. This specifies actually a quota how much size the repository is allowed to occupy and rejects saving files if the quota is reached.

This option is not yet implemented in rustic_server, IIRC, but would be a worthwhile extension.
