Reason/Context

• Adding a new command/flag is a tedious task with current code of the Microcks-CLI. Also, we have to write help for new command/flag explicitly in help command.
• spf13/cobra library can help us to do these things efficiently.

Description

• Currently, we are not using the spf13/cobra library and are instead adding commands and flags using the flag package in Golang.
• For future improvements, using spf13/cobra will make it easier to add support for new commands and flags efficiently.
• It will also make it easier for new contributors to contribute to Microcks-CLI.
