Add new tools to T2VertexBeamSpot algorithm
New tools implement data collection for alternative beamspot calibration methods. As with the current method data is published as a bunch of monitoring histograms that are read by a separate application (BeamSpotTool). This is going to be a part of HLT so performance is critical, this new tool does not add much overhead to existing algorithm, most of CPU is still spent on tracking and track filtering.
Some details are in JIRA: https://its.cern.ch/jira/browse/ATONLBS-25.
