Unfortunately the CLI doesn't have a great way to non-interactively
modify the description. Your best bet is to use `lxc config show` piped
through `sed` and then piped back into `lxc config edit`, something
like:

lxc config show testcontainer | sed "s/description:.*/description: \"blah\"/" | lxc config edit testcontainer
