Miscellaneous checks from the DAQ doctor

Created by: gladky

There are following checks I discovered in DAQDottoressa code that are not in DAQExpert:

To do/verify

• FerolInvestigator this does many checks
• StreamRateMonitor monitors HLT stream (uses following url to get hlt rate http://es-cdaq.cms/sctest/stream_summary_delayed.php?setup=?&run=?) (individual issue #17 (closed))

To do later:

• CrashDetector detects crashed hosts (individual issue #33)
• AlignmentChecker checks alignment of FEDs

To be skipped:

• SplashAnalyzer detects splash
