push: move obsolescence marker exchange in the exchange module
The obsolescence marker exchange code was already extracted during a previous
cycle. We are moving the extracted functio in this module. This function will
read and write data in the `pushoperation` object and I prefer to have all core
function collaborating through this object in the same place.
This changeset is pure code movement only. Code change for direct consumption of
the `pushoperation` object will come later.
