* There are now two attestation packages on azure. The issuer on the server side is created base on successfully querying the idkeydigest from the TPM. Fallback on err: Trusted Launch. * The bootstrapper's issuer choice is validated by the CLI's validator, which is created based on the local config. * Add "azureCVM" field to new "internal-config" cm. This field is populated by the bootstrapper. * Group attestation OIDs by CSP (#42) * Bootstrapper now uses IssuerWrapper type to pass the issuer (and some context info) to the initserver. * Introduce VMType package akin to cloudprovider. Used by IssuerWrapper. * Extend unittests. * Remove CSP specific attestation integration tests Co-authored-by: <dw@edgeless.systems> Signed-off-by: Otto Bittner <cobittner@posteo.net>
