The os.path.isdir() returns True for symlinks that point to directories,
so we also need to check to make sure it's not a symlink too.

Also cleaning up integration tests that had checks for the empty item
attribute in certain results.

Fixes #7535

fixing problem where ansible would error out because Amazon was saying the group didnt exist yet (needed to wait a few more seconds for amazon to propagate correctly)

Using sets for these operations is dangerous because sets cannot contain
certain object types (such as lists) and their iteration order is
undefined.

This was causing a bug in the env module, due to the fact that we now
pass variables for the module through the templating engine combined
with the fact that we split-up the hostvars and setup variables. As a
result, if a variable in the env lookup had the same name as the variable
in Ansible, it would try and template itself over and over again until
the recursion limit would be hit, at which time an empty string was
returned.

Fixes #7396

Remove colon which breaks installation of 1.6.2.

Rework the description so that it doesn't require the colon, rather
than just wrapping it in quotes.

Since the filter list contains hosts, passing that back to list_hosts()
in the inventoy causes issues when the hostname is an IPv6 address
(with :'s interpreted as group unions). Since we already have the list
of hosts, we should not need to pass that back through inventory a
second time.

The ssl cert check will now respect the http and https proxy
environment settings. The url may also have the username/password
embedded, in which case basic auth will be used to connect to the
proxy server.

Also added some error handling to the fetch_url() call in the
