Issue 6159 - Add a test to check URP add and delete conflict (#6160)

Add URP tests that run if URP_VERY_LONG_TEST environment variable is set
One test spends 6 days and check the 5770 different way of running
the (Add, sync agmt 1, sync agmt 2, Del) sequence on 3 suppliers
and check that when everything is in sync, the entries are the same everywhere
Second test generate crossed entries and conflict entries
 (In theory that should not happen but we have sometime seen them)
And tries to remove one of the entry.
Then once everything is back in sync, it check that the entry are the same
 The second test fails - Apparently there is a problem with URP in that corner case
