Add support to connect to DiceDB other than the default port number 7379 and host as localhost

[roopeshsn]

dicedb-cli is hardcoded to connect only to port number 7379 and host as localhost. Modify it so that it can connect to other than localhost:7379 if the DiceDB is configured to work on a different port number and hostname.

Hey,
just started testing out dicedb, so tried using dicedb cli to connect to dicedb , I do see hostname port can be provided as part of CLI arguments (in latest master atleast i do see these changes)

➜  dicedb-cli git:(master) go run main.go --host 127.0.0.1 --port 7379
Connected to DiceDB. Type 'exit' or press Ctrl+D to exit.
dicedb> SET TEST "HELLO"
OK
dicedb> GET TEST
HELLO
dicedb>
dicedb> exit
➜  dicedb-cli git:(master)

Hello Can you assign this issue to me?

I have changes in dicedb-cli repo. I have made port dynamic now. In program arguments user can pass the port number.
