[FLINK-3700] [core] Remove Guava as a dependency from "flink-core"
**Note: This builds on top of pull request #1853**
Almost all Guava functionality used within `flink-core` has corresponding
utils in Flink's codebase, or the JDK library.
This replaces the Guava code as follows
- Preconditions calls by Flink's Preconditions class
- Collection utils by simple Java Collection calls
- Iterator's by Flink's Union Iterator
- Murmur Hasher calls by Flink's `MathUtil.murmurHash()`
- Files by simple util methods around `java.nio.Files`
- InetAddresses IPv6 encoding code has been adapted into Flink's NetUtils
(with attribution comments)
Some util classes where moved from `flink-runtime` to `flink-core`.
