SFC config model should not have RPC

// (main feature: instantiation of a SFC)

rpc instantiate-service-function-chain {
description
"Instantiates a single service function";
input {
leaf name

{ type string; mandatory true; description "The name of the service function chain to be instantiated."; }

}
output {
leaf name

{ type string; description "The name of the created service function path."; }

}
}

// (RPC for testing)
rpc put-service-function-chains {
description
"Creates Service-Functions";
input

{ uses service-function-chain-grouping; }

}

Also what is difference between "instantiate" and "put" ?
