[AKhatskevich]

Branch: https://github.com/tarantool/vshard/tree/kh/small_patches-1
Issues:
 * https://github.com/tarantool/vshard/issues/121
 * https://github.com/tarantool/vshard/issues/52
 * https://github.com/tarantool/vshard/issues/47

AKhatskevich (3):
  #47: Do not force login/pass in URI
  #52: Allow use existing user
  #121: Introduce destroy module feature

Note: #52 and #121 are bounded:
 1. #52 is tested in #121, because destroy module makes it mutch easier
 2. #121 needs #52, because #121 doesn't delete user, and user exists when
    the vshard is loading back
Note: those patches come together, because they are very small.
