Title: FIX: _checkFloat checks INTEGERS, not datetimes; pyLint compliant corrections

Pull that overrides pull 560.

_checkFloat checks INTEGERS, not datetimes ( fixed wrong copy / paste )
added check for OK keys on addOrModifyMethods
pyLint compliant code ( little bit more ), this is part of the refactor described in [#519] (https://github.com/DIRACGrid/DIRAC/issues/519)
