We are removing VB related functionalities from release tools. This
change removes the hashtreeinfo and generator in verity_utils.py. It
also clears the function args using it.
Bug: 241044073
Test: atest under build/make
Change-Id: Icc298256be6917ffbd40cf4735f8e8092b541c9f
Background in http://go/android-partial-updates. For partial update
(e.g. system-only) or devices with mixed build, the current
fingerprint & device name no longer suffice as the precondition to
install the package.
Therefore, we need to additionally include the per-partition build
props into the ota metadata. We also define a protobuf for the metadata
so it can be extended later. The metadata of the legacy format is also
kept for backward compatibility.
Bug: 151088567
Test: unittest pass, generate an OTA and check the result
