New Alignment PyConf configuration

Create a Moore-like Pyconf configuration for alignment jobs. First steps taken in !203 (merged)

To do:

• test that the same results as old configuration are produced
• add options for UT alignment
• add options for Muon alignment
• adapt tests
• adapt ParticleSelections
• adapt TrackSelections
• clean up unnecessary references to TAlignment

Known problems

• there is an issue with calling the AlignmentAlgorithm just Alignment in gaudiiter.py as in the old configuration

HiveDataBrokerSvc                     FATAL in sysInitialize(): exception with tag=mapProducers is caught
HiveDataBrokerSvc                     ERROR mapProducers 	 
Unknown requested input by LHCb::Alignment::AlignAlgorithm/Alignment : /Event/Rec/Track/AlignTracks .
You can set the OutputLevel of HiveDataBrokerSvc to DEBUG to get a list of inputs and outputs of every algorithm.
	 StatusCode=FAILURE
ServiceManager                        ERROR Unable to initialize service "HiveDataBrokerSvc"
HLTControlFlowMgr                     FATAL Error retrieving HiveDataBrokerSvc
ServiceManager                        ERROR Unable to initialize Service: HLTControlFlowMgr

• currently, running gaudiiter.py with multiple iterations doesn't work, as rewinding the event loop is not working in new configuration. See also !203 (comment 4967171)

• vertices and particles are mandatory inputs to AlignAlgorithm, but should be optional
