The 'server.key' and 'server.crt' can printed to stdin.
The two options are:
`dokku certs:show <app> key > server.key`
`dokku certs:show <app> crt > server.crt`
This will create two files, `server.key` and `server.crt`.
Those files contain the private key and the certificate.
Includes tests.
This hopefully makes it a little easier to work with as the tooling is now based on something in golang core.
- move columnize usage to common plugin
- remove old vendor files
