[feature request] New command for dfclient

[inoc603]

Why you need it?

dfdaemon and dfget is both meant for the client and is packaged together into dfclient. We can merge them into one single command, e.g. dfclient, to make distribution easier and enable new features like configuration validation proposed in #627 .

How it could be?

dfclient [command] [options...]

commands:

• daemon: run dfdaemon
• get: run dfget
• run [command]: run the given command with dfdaemon as http proxy, e.g. df run curl http://xxx
• analyze [image or url]: if no argument is given, check dragonfly's configuration and print possible errors or a summary of the configuration. If an image or a url is given, print how the given target will be handled by dragonfly

The original dfdaemon and dfget can be replaced by simple shell scripts that calls corresponding new command to provide backward compatibility.

Other related information

Maybe there's a better name than dfclient. df is ideal but it's already used by a basic linux tool. dragonfly looks great and is easy to pronounce. dfcli of df-cli is also fine, and shorter than dfclient.

Agree with this idea. IMO using one command is much better. We need to discuss more about the sub commands.
