Whenever a user did that in Checkmk 2.0.0 to 2.0.0p4, <b>all</b> Perf-O-Meters vanished. Instead the error message "Exception: _required_names" was displayed. Internal note: When loading the shipped 'metric' plugins in cmk.gui.metrics that also includes the shipped perf-o-meters. Since *local* perf-o-meters are in a differently named directory, we must also explicitly load "perfometer". On the other hand: We must not (re-)load the perf-o-meters without post-processing them, otherwise we run into the "KeyError: '_required_names'". Change-Id: I9ff7544858fab978d5c3224d9dfe1d300e5fc9bb
