Werk #10580: Memory check plugins: Unify service descriptions

Several Memory check plugins have been unified with respect to their service description, which is now simply "Memory" or "Memory $ITEM$".

In order to use these new service descriptions you have to enable them below {Global settings}, {Use new service descriptions}. Renaming of existing services has many implications - including existing rules, performance data and availability history - these renamings are disabled per default for existing installations. Here you can switch to the new descriptions for selected check types.

Renaming the services will mean you loose all historic data. If you want to rename the services but keep the recorded metrics, you have to rename the RRD files in ~/var/pnp4nagios/perfdata/$HOST$ or ~/var/check_mk/rrd/$HOST$ according to the service name change.

Affected check plugins are:

LI:aix_memory LI:brocade_sys.mem LI:cisco_mem LI:cisco_mem_asa LI:cisco_mem_asa64 LI:db2_mem LI:docker_container_mem LI:esx_vsphere_hostsystem.mem_usage LI:esx_vsphere_hostsystem.mem_usage_cluster LI:fortigate_memory LI:fortigate_memory_base LI:fortigate_node.memory LI:hr_mem LI:huawei_switch_mem LI:innovaphone_mem LI:juniper_mem LI:juniper_screenos_mem LI:juniper_trpz_mem LI:mem.used LI:mem.win LI:netscaler_mem LI:solaris_mem LI:sophos_memory LI:statgrab_mem LI:tplink_mem
