A device resource needs to be registered with the API before being able
to create the `config.json` file that goes in a device.
This means thats the device image is configured and written to an
external drive (e.g: SDCard) *after* the device resource registered.
If any of the above operations fail, there will be an unitialized orphan
device living in the selected application that the user will have to
remove himself.
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
```
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.
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`.

Currently, if `device init` was ran without an application argument, we
attempted to get the application name from the current directory, given
it was a git repository.
This approach led to confusions from time to time, so now we prompt the
user to select one of it's own applications from a dropdown instead of
checking the current directory in this edge case.
