Fix bug for setting ec2 tags

Fix an issue where the ordering of an include statement is processed ahead of the conditional in the included statement,
which required a redundant check to see if a variable was defined rather than short circuiting.

Fixes #4469

Fixed broken force=yes on files for directories

in ansible.cfg.

Have the parser explain another type of YAML gotcha to reduce the need for users to ask how to resolve it.

A small refactoring of the authorized_key module to accomodate these
changes, plus fixing some things like not rewriting the file on every
new key. These changes bring the original feature for ssh options in-
line with the comments in #3798

Fixes #3785

Corrected docs

Corrected docs ("monitor" -> "monitoring" and dissociated monitoring from instance_tags in examples)

Template sudo_user via with_items

Fixes #4458

Fixed crash when s3 bucket did not exist for put operation

This oneliner change allows apt-key to inherit the http_proxy variable.

GH-4452 Corrected config load order to match docs
