push: explicitly feed pushop to localphasemove Now that pushop is holding all the push related data, we do not really need a closure anymore. So we start feeding the object to `localphasemove` and will make it a normal function in the next commit.

push: move local lock logic in pushoperation During push, we try to lock the local repo to move local phase according to what we saw/pushed on the remote repo. Locking the repo may fail, in that case we let the push proceed without local phase movement (printing warning). This mean we have code in phase synchronisation that will check if the local repo is locked or not. we need to move this information in the push object to be able to extract the phase synchronisation in its own function. This is done as a boolean because putting reference to the actual lock outside of the main function sounded a bad idea.
