Dict comparisons insensitive to order #1788

Description of issue or feature request:
In #1783 we dropped support for Python 3.6 and inside this pr, we decided to drop OrderedDicts as well: e3b267e.
The argument was that inside python 3.7+ dictionaries insertion order is preserved: https://docs.python.org/3/whatsnew/3.7.html.

Even though the insertion order is preserved we should keep in mind that there are still differences between OrderedDicts and regular dictionaries like when comparing them:

>>> OrderedDict([(1,1), (2,2)]) == OrderedDict([(2,2), (1,1)]) 
False
>>> dict([(1,1), (2,2)]) == dict([(2,2), (1,1)]) 
True

The question is:
Is it a problem if we have two dictionaries with data in a different order that are not the same?

If yes we have two solutions:

• revert e3b267e
• inside the __eq__ implementations make sure this will happen:

>>> list(dict([(1,1), (2,2)]).keys())  == list(dict([(2,2), (1,1)]).keys())
False

or in other words where we are using dictionaries make sure when comparing them that the order makes a difference.
