Ceilometer tests are failed with message ceilometer-api is not running

[Tatyanka]

All service ceilometer tests https://product-ci.infra.mirantis.net/job/8.0.system_test.ubuntu.services_ha.ceilometer/85/#showFailuresLink are failed with
ceilometer-api count not equal to 1
in test output:

ceilometer-api \n: ['16728 ? Z 0:00 [ceilometer-api] <defunct>\n', '28259 ? Ssl 0:18 /usr/bin/python /usr/bin/ceilometer-api --config-file=/etc/ceilometer/ceilometer.conf --log-file=/var/log/ceilometer/ceilometer-api.log\n']

when actually it is run:
http://paste.openstack.org/show/482660/, we need to fix tests.

(According to we set in ceilometer conf that w are use several workers we may receive one of the child process with z status) and test should handle this situation

Tag swarm-blocker is set due to this bug fails 7 test cases (2.0%).

    Fixed Ceilometer and Heat SWARM tests

    We need to fix checks for ceilometer-api processes
    because we shouldn't hardcode count of processes in
    automated tests.
