In FilePeekerLib, handle the case where we get a
MetaCont<IOVMetaDataContainer> rather than IOVMetaDataContainer itself.

 - iteritems
 - coerce iterator to list

Update the handling of CORAL attributes to work with both py3 and py2.
Can simplify it now using a pyroot template proxy.

 - xrange -> range
 - take basestring from past.builtins
 - long
 - take reload from imp
 

In python, if TFile.Get fails, it returns a null TObject object, which is
distinct from None.  So comparing the result of Get() against None is wrong;
better to use not or convert to a bool.

This bug caused peeking in certain old data files to fail.
Fixed.

Enable flake8 for all python modules and make them compliant.

Move code from begin/endRun to start/stop as the former is deprecated.

Initial python3 port.  Not yet meant to be complete; only enough to run
basic athena/configuration jobs.

Update coral attribute method workaround for gcc7.
