bug fix in member_config for having _id > 255

[yuhanz]

I encountered this problem of having _id > 255 where mongodb considers it as invalid _id. The current recipe will get max_id += 1, which leads _id to grows to the top value.

The validation logic is here: https://github.com/mongodb/mongo/blob/master/src/mongo/db/repl/member_config.cpp#L225

To fix the problem, instead of using max_id +=1, we pick a value between [0,255] for _id, excluding the _id's have existed in the member configs.
