change monitoring config to be less expensive for histogram merging
this MR is in response to https://its.cern.ch/jira/browse/ATLASDQ-1192 , which reported histogram merging was expensive for some plots. This changes the configuration to avoid use of alphanumeric axis (labels) on currently highly populated plots. Changes apply to:
Developer/jFexSimMonAlg/h_mismatched_EmulatedTowerEvts
Developer/jFexSimMonAlg/h_mismatched_entries
Developer/eFexSimMonAlg/h_mismatched_EmulatedTowerEvts
Developer/eFexSimMonAlg/h_mismatched_entries
Developer/gFexSimMonAlg/h_mismatched_entries
Changes x-axis from LBN+EventNumber to just LBN, so that axis is numeric
