Documented in resize

#' Resize a droplet by power off, snapshot, and create new droplet
#'
#' @export
#' @param droplet A droplet, or something that can be coerced to a droplet by
#'   \code{\link{as.droplet}}.
#' @param delete_original (logical) Delete original droplet. Default:
#' \code{TRUE}
#' @param ... Named options passed on to \code{\link{droplet_create}}.
#' @return A droplet
#' @details Note that you can not resize a droplet while it is powered on.
#' Thus, this function powers off your droplet, makes a snapshot, then
#' creates a new droplet from that snapshot. We use \code{\link{droplet_wait}}
#' in between these steps to wait for each to finish. You can optionally delete
#' the original droplet.
#' @examples \dontrun{
#' d <- droplet_create()
#' d # current size is 512mb
#' d %>% resize(size = "2gb")
#' }
