Triggered write event for kvt (#2351)
* bump rockdb

* Rename `KVT` objects related to filters according to `Aristo` naming

details:
  filter* => delta*
  roFilter => balancer

* Compulsory error handling if `persistent()` fails

* Add return code to `reCentre()`

why:
  Might eventually fail if re-centring is blocked. Some logic will be
  added in subsequent patch sets.

* Add column families from earlier session to rocksdb in opening procedure

why:
  All previously used CFs must be declared when re-opening an existing
  database.

* Update `init()` and add rocksdb `reinit()` methods for changing parameters

why:
  Opening a set column families (with different open options) must span
  at least the ones that are already on disk.

* Provide write-trigger-event interface into `Aristo` backend

why:
  This allows to save data from a guest application (think `KVT`) to
  get synced with the write cycle so the guest and `Aristo` save all
  atomically.

* Use `KVT` with new column family interface from `Aristo`

* Remove obsolete guest interface

* Implement `KVT` piggyback on `Aristo` backend

* CoreDb: Add separate `KVT`/`Aristo` backend mode for debugging

* Remove `rocks_db` import from `persist()` function

why:
  Some systems (i.p `fluffy` and friends) use the `Aristo` memory
  backend emulation and do not link against rocksdb when building the
  application. So this should fix that problem.
