Description

Plan:

1. add shaded Guava project
2. change all internal uses of Guava to use o.a.j.oak.guava.* (or replace by JDK methods)
3. remove all Guava uses in public APIs (separate ticket)

Note: IDEs do not work well with the shade plugin. In Intellij, you'll have to "ignore" the oak-shaded-guava project ("maven" window). In Eclipse, you even need to remove it. The alternative would be to move the whole subproject outside the Oak reactor pom (opinions?).

Note 2: the current proposed patch uses Guava 20, as it is mostly (OAK-10151) compatible with Guava 15 and allows us to migrate away from APIs that were removed in version 21. Once done with that, we'd update to newer Guava versions.
