Multi-IOV weak mode constraints (Backport of #13710) #13711

Conversation

Feature allows to constrain the tracker alignment procedure to avoid the introduction of weak modes.
Includes extension of the existing code to support multi-IOV alignments + clean-up of existing code.

Presented at Tracker Alignment meeting 16 March 2016:
https://indico.cern.ch/event/504824/session/0/contribution/65/attachments/1244395/1831868/talk.pdf

Backport of #13710

  Introduced some C++11 features to streamline the code.
 - Create constraint configurations for each IOV.
 - technically working: compiling and pede does not complain
   -> Need to verify that the result looks as expected
 - empty IOVs are problematic because the associated parameters are removed by
   pede's cut on the number of hits (since there are 0 hits)
   -> either ignore IOVs by providing a list of IOVs
      or use pede option 'skipemptycons' (preferred)
 - default (next level) behaviour can be changed now
 - added configuration flag to apply constraint at lowest level
