Failing ambassador rolling updates tests

[axsaucedo]

Currently the test_rolling_update10 and test_rolling_update5 are failing consistently for the ambassador tests, whilst passing on the istio tests. This can be reproduced locally by running the tests with the following commands:

pytest  -v -s --capture=no --log-cli-level=DEBUG test_rolling_updates.py::TestRollingHttp::test_rolling_update5

pytest  -v -s --capture=no --log-cli-level=DEBUG test_rolling_updates.py::TestRollingHttp::test_rolling_update10

The tests run for the 5 retries and fail on each, whilst passing on the istio configuration.

Unlikely will look at until Ambassador update or deprecation
