Adds Reconstruction performance reporting to DashBoard, fixes #4329
Configure T1 disk sites overrride

Allow a configurable list of SEs where the Disk node
should have priority over the Buffer, this is used
by T1 sites where the Disk instance is commissioned
and uses the same SE endpoint as the Buffer instance.

It defaults to the SE of CNAF and the Disk SE of RAL. It can be configured
as:

config.PhEDExInjector.diskSites = ["storm-fe-cms.cr.cnaf.infn.it","srm-cms-disk.gridpp.rl.ac.uk"]

Implement deterministic pileup support

The EventAwareLumiBased and LumiBased splitting algorithms
will keep count of the number of jobs when deterministic
pileup is required, this allows the PSet to be tweaked
to use sequential pileup and skip the events already
used from the pileup dataset.
