Improvements

[UCB-3731] - Unity ID Auth Support for ADBV2 Asset Import Caching

Detail: You can now restrict access to an Accelerator to only Unity ID authenticated users. You will need a TLS certificate and key for the Accelerator, and you will need to configure the allowed Organization. From the command line `unity-accelerator config help`:

ProtobufTLSRequired bool
If set true, the Protobuf/Asset-Pipeline-V2 service will require TLS. Almost always used with ProtobufAuthRequired. Only Editor versions 2021.2+ support this feature.

ProtobufAuthRequired bool
If set true, the Protobuf/Asset-Pipeline-V2 service will require authentication/authorization. Requires ProtobufTLSRequired also be set true. Only Editor versions 2021.2+ support this feature.

CertPEM string
The path to a PEM file containing the TLS certificate for the accelerator to use.

KeyPEM string
The path to a PEM file containing the private key of TLS certificate for the accelerator to use.

OrgID string
The Unity Organization identifier that this accelerator serves requests for. This will be set automatically when enabling Collaborate. With Protobuf/Asset-Pipeline-V2, this is only used if ProtobufAuthRequired is set true.
