Test failure: invalid_datasource_name

[khansaad]

Describe the bug
invalid_datasource_name test added as part of create_experiment API tests in the LM mode is failing due to incorrect input being passed to the API.

How to reproduce it
Run the create_experiment LM negative test:

pytest test_create_experiment.py::test_create_exp_invalid_tests --html=/tmp/create-exp.html --cluster_type openshift

Notice the invalid_datasource_name failure with the assertion failure:

>       assert data['message'] == expected_error_msg
E       AssertionError: assert 'Can not spec...er experiment' == 'Given dataso... is not valid'
E         
E         - Given datasource name - invalid-ds either does not exist or is not valid
E         + Can not specify namespace data for container experiment

Expected behavior
Test should pass after fixing the input passed to the create experiment API in the test function def test_create_exp_invalid_tests()
