Options defines the set of options used for grpc keepalive. The Time and Timeout options are used for both client and server connections, whereas MaxServerConnectionAge* options are applicable on the server side only (as implied by the options' name...)
DefaultOption returns the default keepalive options.
AttachCobraFlags attaches a set of Cobra flags to the given Cobra command.
Cobra is the command-line processor that Istio uses. This command attaches the necessary set of flags to configure the grpc keepalive options.
