 DERBY-4834 Add helper class for working with index statistics in JUnit tests
 
-DERBY-5681 added some tests to upgrade statistics procedure test but since that procedure
doesn't exist in 10.4 and before, I added those tests to a new class, namely Derby5681Test.java.
Also, because of the absence of update statisitcs procedure and DERBY-5702, we can't quite
create a hanging statistics row in 10.4 and before. The test in 10.4 will just have a test
to drop constraint(that shares a backing index with another constraint) and show that it doesn't
break anything.
+Have backported the changes to 10.4 but in trunk , for this jira, we added some tests which
use upgrade statistics procedure but since that procedure doesn't exist in 10.4 and before,
the new tests for this jira from trunk couldn't be backported to 10.4 without changes. In
10.4, I added those tests to a new class, namely Derby5681Test.java and these tests donot
use update statisitcs procedure. But, because of the absence of update statisitcs procedure
and DERBY-5702, we can't quite have a statistics row for a constraint which shares a backing
index in 10.4 and before. The test in 10.4 will just have a test to drop constraint(that shares
a backing index with another constraint) and show that it doesn't break anything. Once DERBY-5702
is fixed and backported to 10.4 and before, we will have a statistics row for a constraint
which shares a backing index and we will be able to show that as a fix of this jira, that
statistics row will get dropped when the constraint is dropped.
