Now I Know that According to the docs, EEST is not a supported timezone. But what Am I supposed to do in this case?

Transform it into something that is has the same offset from UTC, but is supported. According to Wikipedia Moscow time is the same as EEST.

mutate { gsub => [ "logdate", "EEST", "Europe/Moscow" ] }
