pull: introduce a pulloperation object
This object will hold all data and state gathered through the pull. This will
allow us to split the long function into multiple small one. Smaller function
will be easier to maintains and wrap. The idea is to blindly store all
information related to the pull in this object so that each step and extension
can use them if necessary.
We start by putting the `repo` variable in the object. More migration in other
function.
