Update version info endpoint

This commits updates version endpoint to use ProviderInfo and VersionInfo structs from
faas-provider.GatewayInfo now uses ProviderInfo and VersionInfo structs. GatewayInfo is
left within gateway. Consumer of this endpoint should use typed struct GatewayInfo to
parse response.
