In my system (MBPr 13), printing the current version takes over 2
seconds:
```sh
$ time ./bin/resin version
2.4.0
./bin/resin version 1.37s user 0.19s system 73% cpu 2.130 total
```
The CLI takes almost all of these time to parse the dependency tree
before returning control over the actually called command.
To mitigate this problem, we only require the NPM dependencies a command
requires when executing such command, and thus prevent dependencies from
being required and parsed unnecessary.
After this improvement, printing the original example (`resin version`)
returns in less than a second (2x improvement):
```sh
$ time ./bin/resin version
2.4.0
./bin/resin version 0.88s user 0.09s system 102% cpu 0.938 total
```
This is useful in the scenario when the user is using the CLI in an
environment in which he/she doesn't have access to a web browser, like a
headless server or a Vagrant development environment.
When you change the `resinUrl` config from time to time it can be
confusing to remember where you're logging in, or in which host you're
in.
Currently I have to check the configuration files/environment variables
manually or run `resin settings`.
This PR prints the detected resin url on `resin login` and `resin
whoami` so it's always clear where you are.
The command to get information about a device, `resin device` requires a
`uuid` as a parameter. Given that we don't show uuids in `resin
devices`, the user has no way to know what uuid to pass to get extra
information.
We also remove some non very used information columns from `resin
devices` to make space for the uuid.
The last part of `quickstart` feels weird. By consensus, we remove the
part that attempts to create a project directory and leave that step to
the user.
This allows the user to bypass the drive selection dialog.
This option can be used along with `--yes` to make the command
completely non-interactive. For example:
$ resin os initialize rpi.img 'raspberry-pi' --drive /dev/disk2 --yes
Currently, the fact that `os initialize` requires elevated permissions
forced us to require calling commands that reuse it, such as `device
init` and `quickstart` with administrator permissions as well.
This ended up causing issues like saving images in the cache that belong
to root, or initializing git repositories that requires `sudo` to
commit.
The solution is to call `os initialize` as a child process preppending
`sudo` within `device init`.
