`rune` is alias for `int32`. `randString()` used `rand.Int()`
which returns system-specific non-negative integer number. For
64-bit systems it will be int64. An attempt to cast `int64` to
`int32` (`rune`) leads the latter to be a negative number in
case of overflow. This caused the resulting string containing
unexpected symbols.

It is the heaviest function executing on setup stage.
The culprit is the linear dependency between its execution
time and the amount of objects in registry. The solution is to store
object by status. While the optimization doesn't work for objects with
no status, it is currently provided by all scenarios.

1. Get rid of JSON in the database.
2. Store `CreatedAt` as int64. It decreases JSON marshaling time by
about ~25% with no changes for native scheme.
