Otto Bittner 405db3286e AB#2386: TrustedLaunch support for azure attestation
* 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
