[BUG] KV boltdb permissions

[SerafimArts]

I tried this code:

kv:
  first:
    driver: boltdb
    interval: 60
    file: "rr.db"

Then execute RR server twice:

$ rr serve
Ctrl+C (stop server)
$ rr serve

I expected to see this happen: All OK (default permissions is 0777)

Instead, this happened:

open rr.db: Access is denied.

The version of RR used: 2.3.0 (stable)
