L1 rate check enhancement

Created by: gladky

There is a LM RateOutOfRange which checks if rate (FedBuilderSummary.getRate) is within the limits. Min and max value are set in configuration file:

expert.l1.rate.min=50000
expert.l1.rate.max=100000

Do we want more precise check based on current conditions (similar to expected HLT rate check)?
