add loose comparison in some unit tests
For instance Multi-node testing loop / freebsd-64-latest / results / RebindTest.requestPrefixInRebind failed with:
rebind_unittest.cc:948
Expected: 1000
To be equal to: leases_client_na_rebound[0].cltt_ - leases_client_na[0].cltt_
Which is: 1001
it is obviously a timing issue. I propose:
- create a generic tool for handling this case if it does not yet exist
- use it beginning by this test
