[BEAM-2982] Use the SubscriptionProvider in PubsubUnboundedSource
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).

time.
