Commands like "droplets" need formatting switches

Commands like "droplets" need formatting switches to do things like only list IPs to avoid stuff like:

tugboat droplets | grep -F TEST | cut -d : -f 2 | cut -d ' ' -f 2 | cut -d , -f 1 >>big-test-hosts

Makes sense.

Hmm, this would probably be easiest by extending the porcelain mode from the info method into the droplets method.

$ tugboat info -n foo-node --porcelain --attribute=ip4
10.0.1.1

How would you like it to look when it outputs, something like this:

$ tugboat droplets --porcelain --attribute=ip4
foo-node, 10.0.1.1

@adamierymenko Can you give an example of how you want it to look?

Do you want a CSV style output like we do for info and --porcelain mode:

$ tugboat droplets --porcelain --attribute=ip4
foo-node, 10.0.1.1
foo-node2, 10.0.1.2

[adamierymenko]

CSV would be fine, and ditch the extra spaces since it requires an extra 'cut' or 'sed' etc. from the command line. Goal is to make it easy to script stuff.

Could also do an output format flag: csv, yaml or JSON 👍

@adamierymenko Are you still using tugboat? Bit late now (2 years!) but I finally got this working now:

$ tugboat droplets --attribute=ip4
test-blog-1,41.101.11.22
test-blog-2,138.68.11.22

Got it up as a PR here: #294
