Requirement:
The user able to define SNMPv3 data plane packet headers. Purpose is to flood DUT with SNMPv3 request and responses. The user should be able to configure different fields in Global Data, Security Parameters and Data with ability to specify Increment/Decrement operations on certain applicable fields in the specified fields.

Example usage:

        f1 := config.Flows().Items()[0]
	f1.SetName("flow-snmpv3").
		TxRx().Port().SetTxName("port1").SetRxName("port2")

	f1.Duration().FixedPackets().SetPackets(100)
	f1.Rate().SetPps(10)

	f1.Packet().Add().Ethernet()
	f1.Packet().Add().Ipv4()
	f1.Packet().Add().Tcp()

	// SNMPv3 Header
	flowSnmpv3 := f1.Packet().Add().Snmpv3()

	// Version
	flowSnmpv3.Version().SetValue(3)

	// Global Data
	globalData := flowSnmpv3.GlobalData()
	globalData.Id().SetValue(1)
	globalData.MaxSize().SetValue(100)
	globalData.Flags().
		SetReportable(true)
	globalData.SecurityModel().SetValue(1)

	// Security Parameters

	// No Authentication
	securityParams := flowSnmpv3.SecurityParameters()
	securityParams.SetAuthoritativeEngineId("80004f4db1aadcadbc89affa118dbd53824c6b05")
	securityParams.AuthoritativeEngineBoots().SetValue(3)
	securityParams.AuthoritativeEngineTime().SetValue(68125)
	securityParams.SetUserName("tchyon")

	// Data
	plainText := flowSnmpv3.ScopedData()
	plainText.SetContextName("tchyon")
	plainText.SetContextEngineId("80004f4db1aadcadbc89affa118dbd53824c6b05")
	pdu := plainText.Data().GetRequest()
	pdu.RequestId().SetValue(722681733)
	pdu.SetErrorStatus(gosnappi.FlowSnmpv2CPDUErrorStatus.WRONG_VALUE)
	pdu.ErrorIndex().SetValue(0)
	varBinds := pdu.VariableBindings().Add()
	varBinds.SetObjectIdentifier("0.1")
	varBinds.Value().TimeticksValue().SetValue(20)

	// Authentication

	md5 := securityParams.AuthenticationParameters().Md5()
	md5.SetPassword("abcd")
