v1.1.7 or later fails when building images in parallel
Overview of the Issue
Ever since v1.1.7, some of our windows builds have been failing with the error
"Error creating windows password: time out while waiting for the password to be created"
On a hunch, instead of having packer use oslogin to create the packer user we created the packer user in a startup script. We then started getting the error
"errored after 12 seconds 726 milliseconds: Error importing SSH public key for OSLogin: googleapi: Error 409: Multiple concurrent mutations were attempted. Please retry the request."
Reverting back to v1.1.6 of the plugin avoids all these errors.

This seems to happen with Linux hosts too. Well, not the "windows password" error, but the "Multiple concurrent mutations were attempted" one. :)
I've tried the newest 1.2.1 of the plugin and then downgraded 1.1.6 as suggested above, but that didn't seem to help.
Packer version is 1.13.1.
