DO SSH fingerpring change.
DO SSH fingerpring change.

This is a slight change to the DO UI template.
The DO api requires the fingerprint option now. The
template has been changed to require the fingerprint.
i.e. You must provide a fingerprint for DO kubes.

example:

```
"ssh_key_fingerprint": ["xx:xx:xx:xx:xx", "xx:xx:xx:xx:xx"]
```
