* remove mod_evasive which is potentially installed by apache2_module integration test and add zabbix_host to CI
The tests pass when run in isolation, but when run as part of the posix/ci/group1 tests they fail.
* Integration tests for zabbix_host using Zabbix on Ubuntu 14.04. * fix duplicate yaml key in test * .changed -> is changed, |failed -> is failed, trim configfile * zabbix_host integration test does not need BOTMETA entry, inherited from module
