Fix statistics of Trend plots

[mbandrews]

Fix Presample and Timing Trend plots

• Create new set of Task MEs that only contain statistics from "current LS" which the Client Trend plots will analyze
• Define "current LS" = 10 LSs (10 LSs = 1 pt in the Trend plots) and we want to collect sufficient stats so that different channels are well-represented beyond the minChannelEntries threshold
• Include a filter to exclude channels with status other than EcalChannelStatusCode::kOk.
• Previously, Trend plots were using cumulative statistics causing noisy channels to accumulate enough stats to bias trend which resulted in "jumping" phenomenon after plot resets
• See 80X PR Fix statistics of Trend plots #14517

This pull request is fully signed and it will be integrated in one of the next CMSSW_8_1_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @slava77, @davidlange6, @Degano, @smuzaffar
