Use separate prompts for downgrade in cases of incompatibility or wrong channel

Using custom SSL certificate properly configured, and using a Drive client version having NXDRIVE-1497 implemented, you can still have a discrepancy between a Nuxeo Server side matching the documented requirements and a Client claiming it must downgrade for compatibility reason.

In this case, it is not really incompatible, it's just using a version from another channel. We should explain it properly and ask if the user wants to either switch channel to the one corresponding to his current version or to downgrade to the latest version of his current channel.
