Upgrade client-go to v12.0.0

Minor API changes (some helpers functions disappeared upstream probably because they were deemed to be trivial to write explicitly).

Sore point: a roundtrip test is broken since the reflection based test trips over some non-semantic changes while comparing empty slices (nil != []foo{} in Go)
Will address that ASAP but I'd like to unblock this in the meantime.

Closes #183
