can `StringAppender::transform()` be removed, too?

this seems to be the only place where we use
`RocksDbInstance::db_options_patch_`; can it be removed?

Review comment:
why is this cast needed? `FlowFileRepository::ENCRYPTION_KEY_NAME` is
already a `const char*`

Review comment:
we already have `utils::crypto::randomBytes()` in EncryptionUtils which
does the same thing (but instead of libressl it uses libsodium, which is better
according to @alopresto)
