Remove `do_` prefix from droplets functions

[sckott]

Yeah, probably not needed, though some fxns I worry may conflict like keys or regions

I'd make them start with droplet_ and take a droplet as first argument. e.g. do_droplets_power_on would become:

droplet_power_on <- function(droplet, ...) {
  path <- sprintf('droplets/%s/power_on', droplet$id)
  do_GET(path, ...)
}

To make the droplets functions even more useful, they should always return a droplet object. Then you could use %>% to pipe multiple operations together.

[sckott]

Starting with droplet makes sense. Good idea to facilitate use of %>%
