Add goleak to all tests (#227)

* Run goleak as part of all tests
We are already using goleak in various tests.
This commit adds a TestMain to all remaining tests
and calls goleak.VerifyTestMain in them.
* Add goleak to debugd/deploy package and fix bug.
* Run go mod tidy
* Fix integration tests
* Move goleak invocation for mount integration test
* Ignore leak in state integration tests
