[Feature]: Use GCP IAM when pulling docker images from Google Artifact Registry

[colinjc]

Problem

When launching a VM on GCP that uses an image stored in a private GAR the only documented approach for getting access is to use the registry_credentials option in the .dstack.yml. This is very manual and unfriendly.

Solution

When pulling images from GAR dstack should use the IAM permissions of the server and VM to authenticate automatically.
