Cover more flows in c2d flow integration test

[bogdanfazakas]

Cover the following situations:

• publish algorithm and dataset with compute service using the 2nd provider
• publish an algorithm with CustomData
• publishes dataset with a compute service that allows Raw Algo
• should publish a dataset with a compute service object that allows only a certain algorithm to run on
• check not allow a compute job with dataset/algorithm compute services served by different providers
• check not allow a compute job for dataset compute services that allows only certain algo
• try start a compute job with a dataset on provider1 and published algo on provider2
• check not be able start a compute job with a published algo that requires userdata without providing that
