    [BEAM-2729] Allow GBK of union-typed PCollections.

    Follow this checklist to help us incorporate your contribution quickly and easily:
    
     - [ ] Make sure there is a [JIRA issue](https://issues.apache.org/jira/projects/BEAM/issues/)
filed for the change (usually before you start working on it).  Trivial changes like typos
do not require a JIRA issue.  Your pull request should address just this issue, without pulling
in other changes.
     - [ ] Each commit in the pull request should have a meaningful subject line and body.
     - [ ] Format the pull request title like `[BEAM-XXX] Fixes bug in ApproximateQuantiles`,
where you replace `BEAM-XXX` with the appropriate JIRA issue.
     - [ ] Write a pull request description that is detailed enough to understand what the
pull request does, how, and why.
     - [ ] Run `mvn clean verify` to make sure basic checks pass. A more thorough check will
be performed on your pull request automatically.
     - [ ] If this contribution is large, please file an Apache [Individual Contributor License
Agreement](https://www.apache.org/licenses/icla.pdf).
