Description

Implement the following "interface description" series commands:

interface description <port number> <description>: add a description to a port (except management port).
no interface description <port number>: delete a description to a port (except management port).

We use JSON to store the description ("description": "<your description>") in the corresponding ifalias of an interface. 
What's more, user can check the description using show interface.

Testing Done


(PASSED) The port with interface description set should show the description using show interface.

Description:

		Implement the following "interface description" series commands:

~		`interface description <port number> <description>`: add a description to a port.
~		`no interface description <port number>`: delete a description to a port.
	~	`interface description <port number> <description>`: add a description to a port (except management port).
	~	`no interface description <port number>`: delete a description to a port (except management port).

~		We use JSON to store the description (`"description": "<your description>"`) in `ifalias`.
~		When deleting the description attribute after executing `no interface description` (therefore, an empty content of JSON will appear in `ifalias`).
	~	We use JSON to store the description (`"description": "<your description>"`) in the corresponding `ifalias` of an interface.
	~
	+	What's more, user can check the description using `show interface`.

Testing Done:

~		(PASSED) The `ifalias` should appear a JSON with content of `{"description":"<your description>"}` after executing `interface description`.
	~	(PASSED) The port with `interface description` set should show the description using `show interface`.
-		(PASSED) The `ifalias` should appear a JSON with content of `{}` after executing `no interface description`.
