Review request for atlas and David Kantor.
Bugs: ATLAS-1535
https://issues.apache.org/jira/browse/ATLAS-1535
Repository: atlas
Description (updated)
-------
When debugging some of the test failures in webapp, I found that many are
occurring when a http request runs in the context of a stale Titan transaction.
There is logic in BaseService to rollback the transaction associated with a
thread whenever a new request comes in. However, this logic is not used in all
places.
This changes add logic to fix this. I've added a new filter to consistently
clean up stale transactions when processing http requests. I removed the old
logic, which was only used by two service classes. The new filter is applied
for every http request that comes in, so the transaction used during request
processing will never be stale now.

Testing
-------
Ran webapp tests. Now, we're only left with the following failures:
QuickStartIT.runQuickStart:44 » AtlasService Metadata service API
org.apache.a...
QuickStartV2IT.runQuickStart:47 » AtlasService Metadata service API
org.apache...
NotificationHookConsumerIT.testUpdatePartialUpdatingQualifiedName:170
expected:<0> but was:<1>
Previously, there were a number of other tests that were failing sporatically
with a NullPointerException coming from Titan. These changes fix that.
Thanks,
Jeff Hagelberg
