This is a preliminary change to move the code that chooses what network gets assigned to what request out of ConnectivityService. By storing the list of changes first, it becomes possible to move the changes with side-effects to a later part of the code, after the decisions have been made. This move is implemented in a later change. Bug: 113554781 Test: ConnectivityServiceTest Change-Id: I60fe318a8eabf13d1c07b144367ca92cf07e734e
