Code review comment for lp:~bac/launchpad/ec2_attached

= Summary =

Using 'ec2 land' the use of --headless is hard-coded. This branch adds
an '--attached' option for the very rare cases you don't want to use
headless.

== Proposed fix ==

Simply add the option to make --headless the default but optional.

== Pre-implementation notes ==

None.

== Implementation details ==

As above.

== Tests ==

None.

== Demo and Q/A ==

Run 'ec2 land --dry-run' with and without --attached
