Add support for new payload property headers to delay switching slots.
Set SWITCH_SLOT_ON_REBOOT=0 to skip marking new slot as active.
When ready to reboot to the new update, call applyPayload() again to
switch the slots, download will be skipped because it has already
finished, filesystem verification will always happen, and postinstall
can be skipped if it succeeded before for this update and
RUN_POST_INSTALL is set to 0.
Also removed reset update progress when update succeeded to support
reverting to current slot with resetStatus() without clearing download
progress. If the next update is a different payload then we will still
reset the progress on next update.
