Original change's description:
> [ffx][flash]: flash uses event based reconnect
>
> Now, in the flash process, when rebooting the bootloader (after flashing
> the new bootloader) instead of using a configurable sleep to wait for
> the target to reappear (and continue to flash the product), the tool
> will use the discovery library to begin looking for the target to
> reappear in fastboot mode.
>
> This assumes:
>   1. A target will never change fastboot connection mechanisms. For
>      example, it is assumed that if a target is connected via USB, after
>      the bootloader reboots it will continue to be available via USB
>   2. A target's name (for fastboot over TCP/UDP) is consistent across
>      reboots.
>   3. A target's serial number (for fastboot over USB) is consistent
>      across reboots.
>
> Release-Notes: ffx no longer uses the daemon for flashing.
