> Secure Dictionary Server Port Implementation.
> During single pass load  Dictionary key creation is done through driver and executor
communication through external ports. The communication will happen through TCP communication
which is not secure or encrypted.
> But in case spark turn on Security parameters then carbon dictionary ports also has to
follows same authentication and encryption i.e. communicate through SASL Authentication protocol
and Digest-MD5 encryption.
> This PR makes the dictionary server and client communication Secure and encrypted. In
case spark turn ON security and authentication through the below parameters then Carbon communication
also becomes secure. 
> By default the communication is still non secure. 
> Parameters 
> *spark.authenticate true
> spark.authenticate.enableSaslEncryption true
> spark.authenticate.secret*
