    [BEAM-419] Fixing SE_BAD_FIELD FindBug in CombineFnUtil

    Follow this checklist to help us incorporate your contribution quickly and easily:
    
     - [x] 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.
     - [x] Each commit in the pull request should have a meaningful subject line and body.
     - [x] Format the pull request title like `[BEAM-XXX] Fixes bug in ApproximateQuantiles`,
where you replace `BEAM-XXX` with the appropriate JIRA issue.
     - [x] Write a pull request description that is detailed enough to understand what the
pull request does, how, and why.
     - [x] 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

    FindBugs detected that the `context` member in `NonSerializableBoundedKeyedCombineFn`
(now `NonSerializableBoundedCombineFn`) was not serializable although the class was. Seeing
as the class has "`NonSerializable`" right in the name, to fix the FindBug I marked the member
as transient to make it explicitly non-serializable.
