Improve ec2 module docs

Change reference to open 'intranet' to 'internet'

Include all man pages in Arch Linux package.

Fix Linode inventory plugin causing a Chube exception when attempting to obtain information on a specific Linode host

While we're on it, change $pkgdesc to follow its counterpart from
official repositories. Additionally don't install RELEASES.txt and
CONTRIBUTING.md; there is little use for them from the user's perspective.

The Internet is being referred to, but the documentation uses the word 'intranet'.

add missing ' in Linode documentation

Refining the fix made in #5885.

Merging this quickly after PR as further testing of of earlier fix demonstrated flaws. Those flaws are now removed and tested to be removed.

It turns out that some of the assumptions in #5885 were slightly off. The previous fix relied on a call to the module to creat a tmp_path. This is insufficent as there are few cases that we need to have the tmp directory before we make the module call. If we don't have a tmp_path before we do a recursive call or when we find a file that does not match the remote md5 hash we need to create a tmp directory. Also we are not more percise when we will need to clean up the remote tmp_path.

This patch makes Ansible reuse fork allocation between seperate instantations of the runner API, therefore the overhead of recreating forks
between tasks in a playbook is avoided.  The fork pool will be regenerated when a second play comes along and needs more hosts.

Added port documentation to postgresql_db and postgresql_user.

Addresses #5739 and cleans up copy.py

Support for -a to accept a file with test-module

If the CLI value for -a starts with an @, treat it like a file, and dump the contents into complex_args

This supports yaml or json.

A fix for uri module regarding following redirects. The old behavior would follow redirects either way. This change clarifies the functionality and makes it a bit more explicit. Comparing the old behavior to the new 'yes' == 'all', 'no' == 'safe' and now 'no' will not follow any redirects. Historic behavior is still supported and documented with a push to the new values.

Add exact_count and count_tag to the ec2 module.

Confirmed that these are small changes to the docs that help with the clarity.

Create a common EC2 connection argument spec for EC2 modules

Refactor the currently well-factored ec2 modules (i.e. those that already use ec2_connect) to
have a common argument spec. The idea is that new modules can use this spec without duplication
of code, and that new functionality can be added to the ec2 connection code (e.g. security
token argument)
