puppet module tool needs to use '--force' on PE >= 3.2.1

[curator]

Per #190, in order to get around a 'supported modules' issue where the puppet module tool will fail install if you attempt to use a module 'supported' by that particular version of PE (such as using a newer stdlib, a common practice), the invocation needs to use '--force' instead of '--ignore-dependencies'.

For what I see here http://docs.puppetlabs.com/references/3.4.3/man/module.html --ignore-dependencies is still needed as force will install the dependencies, isn't it?

[reidmv]

The --ignore-dependencies flag is insufficient to resolve this problem. One of either --force or --ignore-requirements needs to be specified to bypass the 'supported' check.

Note that the --ignore-requirements flag is an addition, and so won't work with older versions of Puppet.

The behavior is demonstrated below with each flag.

[root@master ~]# puppet --version

Notice: Skipping versions which don't express PE compatibility. To install
the most recent version of the module regardless of compatibility
with PE, use the '--ignore-requirements' flag.

@reidmv yes, --ignore-dependencies is not enough, but is it still needed? firewall is not a good example as it does not have dependencies

Give it a try with the mysql module to see if dependency stdlib is installed (clean tmp between calls)

puppet module --modulepath /tmp install puppetlabs/mysql --version 2.2.3 --ignore-requirements
puppet module --modulepath /tmp install puppetlabs/mysql --version 2.2.3 --force
puppet module --modulepath /tmp install puppetlabs/mysql --version 2.2.3 --ignore-requirements --ignore-dependencies
puppet module --modulepath /tmp install puppetlabs/mysql --version 2.2.3 --force --ignore-dependencies

[curator]

I have confirmed that this will definitely work with --force and co-exists with --ignore-dependencies and also replaces it (only the first of your four examples get stdlib installed, the rest successfully ignore all the things requested).

I do, however, note that code paths have changed sufficiently to make my original pull request useless. Would you like me to kill and resubmit or is there enough data to move forward with the change yourself?

Please rebase and you can update the branch with "git push -f" and will update the issue
