install_gcloud now can install components

Now kubectl can be installed with everything else

Please use "$@" instead of $*.

See for example the behavior of:

#!/bin/bash

for i in $* ; do
  echo '$*' $i
done

for i in "$@" ; do
  echo '$@' $i
done

Called with:

$ ./t.sh "a b" "c d"
$* a
$* b
$* c
$* d
$@ a b
$@ c d

Thank you.

LGTM, with a small change.
