Monitoring System

A new DIRAC system Monitoring is introduced. This system is used for collecting and reporting various kinds of monitoring information using ElasticSearch DB as its backend. Currently, this system is used to monitor host and running components information as well as the WMS History information. The old Framework/Monitoring service and possibility to store thw WMS History in the Accounting DB is still preserved if ElasticSearch DB is not available for some installations.
