Detailed bug description:
 We got this test failed in swarm run - https://product-ci.infra.mirantis.net/job/9.0.system_test.ubuntu.thread_3/175/testReport/(root)/check_openstack_stat/

As far as we understand, the problem is in unexpected result returned by query.
There was a string separated by "\n" symbol and the json parser could not handle such a response.

Steps to reproduce:
Check openstack statistic on fuel and collector side
    Scenario:
        1. Revert ceph_ha env
        2. Create all openstack resources that are collected
        3. Check that all info was collected on fuel side
        4. Check that info was sent to collector
        5. Check that info is properly saved on collector side

Expected results:
All steps passed

Actual result:
Test failed with error

Reproducibility:
sometimes

Impact:
