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. Signed-off-by: Vivek Singh <vivekkmr45@yahoo.in>
