The versions Docker that the compat endpoints currently support are
using another type for the `filters` parameter than later versions
of Docker, which the libpod/events endpoint is also using.
To prevent existing deplopyments from breaking while still achieving
backward compat, we now support both types for the filters parameter.
Tested manually.
