[ostf] Murano test "Create and delete Murano environment" fails without any message when Murano service unavailable

[Anastasiia Naboikina]

Steps to reproduce:
1. Deploy a cluster with Murano service.
2. Turn off Murano service.
3. Run OSTF test "Create and Delete Murano environment"

Expected result:
There is a descriptive message about unavailability of Murano service.

Acutal result:
Test failed without any message (see screenshot).
There are the following errors in OSTF logs:
CommunicationError: Error communicating with http://172.16.0.2:8082 [Errno 113] No route to host

A check has to be added that verifies if Murano is available before launching the test.

Considering this as Medium (it doesn't affect functionality and OSTF provides right results, the only is that it doesn't provide information on WHY murano test case fails, when it truly not working). This is still highly-wanted in 4.1 bugfix.
