flash.sh: Rewrite to be more robust and useful for testing
As per b/148225837, the enterprise flashing script needed to support the
following features:
- Flashing specific fastboot devices by serial number
- Optionally not rebooting the board at the end
- Checking for the presence of a specific device with retries
Additionally, this change swaps to using getopt to make option parsing better
for both the user and more robust for the script.
