Repos for SLES and openSUSE

[genebean]

While working on #8 I found that most of the repos for these os's have gone away. Based on looking at https://software.opensuse.org/package/zabbix there are next to no options for Zabbix 3.2. When looking at Zabbix 3.4 the best option seems to be home:pclo:monitoring which has builds for SLES 11 & 12 and openSUSE 42.2 and 43.3. No one seemed to have much of anything for 42.1 anymore either. I propose we:

• move to home:pclo:monitoring for Zabbix 3.4 SUSE / openSUSE repos
• drop repo support for 42.1 and
• drop repo management support for Zabbix versions older than 3.4 on the Suse family

FYI, #8 now removes management of repos on Suse.
