Refactoring: support session/cookie getters and setters

[Ana Krivokapić]

In https://github.com/openstack/horizon/blob/master/horizon/utils/functions.py, there is a function called get_page_size() which is used to get the value of the page size parameter from the session and/or cookie. We should refactor this part of code, by adding a pair of generic getter/setter functions which can be used to get arbitrary values from the session/cookie. More specific functions which deal with particular session/cookie values in specific ways can then be implemented, and they will call the generic getters/setters.

That would be a nice improvement.
