Rattlesnakeos Stack Versions Save

• fix newline version string breaking build

• increase volume size from 300->350GB. closes #197

temporary change: bring your own android-prepare-vendor. due to licensing issues with android-prepare-vendor, this release is no longer providing android-prepare-vendor by default. there are now 3 local config entries that need to be provided.

• apv-remote is the remote that contains the android-prepare-vendor repo (e.g. https://github.com/example/)
• apv-branch is the branch to use (e.g. 12)
• apv-revision the git commit to lock to (e.g. f1d2d2f924e986ac86fdf7b36c94bcdf32beec15). this is a temporary change until an alternative to android-prepare-vendor is built.

changes for latest stable chromium

• fix issue with terraform on init that was giving error 'openpgp: signature made by unknown entity'. this is due to hashicorp rotating their signing keys in response to a security incident (https://discuss.hashicorp.com/t/terraform-updates-for-hcsec-2021-12/23570). fix is upgrading from 0.11.14->0.11.15. closes #190.
