Estimate COW image size and put the estimation in OTA metadata. Then VAB
could use this to allocate disk space and prompt the user if more space
required.
Test: create an OTA package

Update the update_payload scripts to be compatible with
python2 and python3. Python2 compatibility is needed since
the repo is shared with Android.

We have moved away from major version 1 in Chrome OS and already have a
stepping stone for it in M53. So this cleanup makes the code much easier
to understand.

Minor version 1 was for the old days where we rewrite the signle
partition with an update (no A/B partitions). But those days are long
over and we don't think there is any device out that has this capability
anymore. Even if there is, we can always serve full payloads along with
the stepping stone we have in M53. So this is safe to go.
