# SSH Bootstrap
#
# Renders the *content* string into a file on the remote host and proceeds
# to execute it via */bin/bash*. Sudo is prefixed by default, but can be
# disabled.
#
# @example Sample Bootstrap, assuming the @ssh variable is an instance of ZTK::SSH connected to a host.
# @ssh.bootstrap(IO.read("bootstrap.sh"))
#
# @example
# @ssh.bootstrap("apt-get -y upgrade")
#
# @param [String] content What to render out to the bootstrap file we will
# execute.
# @param [Hash] options The options hash. This will also accept options
# for #exec in order to better control the bootstrapping execution.
# @option options [String] :use_sudo True if we should execute the
# bootstrap via sudo; False to execute it as the defined user.
