Lets introduce util helpers to serialize integers using constant amount of bytes.
container.DeletionInfo struct uses epoch and is serialized using variable number of bytes. The problem is when this number changes between test invocation and persist. It can happen only 7 times throughout the network lifetime, so not is that big a deal. But it seems easy to support and also backward compatible (native serialization just strips leading zeroes).

I believe we also have 2-bytes sequences somewhere.

As alternative, client can increase fee on container.Delete and similar operations (fee difference shouldn't be quite large for 1 bit value and 128 bit value, I suppose). But proposed solution is cleaner to me.
