Check cluster settings before and after the deploy

[Dennis Dmitriev]

In https://bugs.launchpad.net/fuel/+bug/1562736, some interface objects are missing in the Nailgun by the end of deploy a cluster.

Looks like it is not affecting the cluster itself, because OSTF passed succesfully.
But we don't know if the cluster was deployed with the settings that system tests requested, not with the some random or missed settings that produce working cluster but with not expected configuration.

We would add a check that will store a cluster settings before each deploy and compare it with the cluster settings at the end of the deploy, to catch the issues with missing objects.

Dennis +100 for such check. It also may be useful in tests for unlock settings tab
