Without this fix you have to enter your vault password before you realize
that you forgot to pass in the filename.  This commit checks that an
filename argument was at least passed on the command line.

It also defaults to the "latest" tag for pulling the image
instead of pulling all versions.

The apache2_module module did not properly handle when a2enmod would
handle apache module dependancies.  It would always return a state of
changed.  I've updated the regular expression to properly parse that
output as well as the normal output.  A good example of this is the
mod_proxy_http module.

Split the error check into two error checks and delay the
checks so that listing existing volumes works more nicely.

The error check should check that:
* One and only one of volume_size id or name is set

This fix adds the 'only one' part of that check and provides
more useful error messages.
