    DRILL-4369: Exchange name and version infos during handshake

    There's no name and version exchanged between client and server over the User RPC
    channel.
    
    On client side, having access to the server name and version is useful to expose it
    to the user (through JDBC or ODBC api like DatabaseMetadata#getDatabaseProductVersion()),
    or to implement fallback strategy when some recent API are not available (like
    metadata API).
    
    On the server side, having access to the client version might be useful for audit
    purposes and eventually to implement fallback strategy if it doesn't require a RPC
    version change.

>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Client - JDBC
>    Affects Versions: 1.4.0
>            Reporter: N Campbell
>
> Using Apache 1.4 Drill
> The DatabaseMetadata.getters to obtain the Major and Minor versions of the server or
JDBC driver return 0 instead of 1.4.
> This prevents an application from dynamically adjusting how it interacts based on which
version of Drill a connection is accessing.
