Release Documentation guide - add a respin documentation

A late respin request has been made for AM1 right before going to QE and i missed some documentation about respin the entire staging update site.
It was only one component to be patched but i decided to respin the entire updates sites.

Is that the right process ?

If yes, i was a little struggled because the release process documented here was for CF only and everything is in place.

a respin/patch documentaion should be created to handle such cases.
