* Fix check_mode for initctl systems

Fixes #9009

This commit also makes the dest parameter optional, unless update=yes
(the default), since it is not required for queries without an update.

Fixes #8630

ansible-galaxy: exit with rc 1 if role doesn't exist/is not found

Fixes #8731

Merge branch 'ec2-tag-filter' of https://github.com/michalgasek/ansible into michalgasek-ec2-tag-filter

Fixes #7844

updated git module documentation

rearrange description/short_description

Document vault_password_file in intro_configuration

Fixes #9016

Also modifies the template action plugin to use this new param
when executing the file/copy modules for templating so that links
are preserved correctly.

Fixes #8998

Clarified key_file option for the git module, since it requires the user to specify a private key, not a public key.

Centos 6.x and below use an old RHT style of configuring hostname.
CentOS 7.x and better use systemd.  Instead of depending on the
distribution string which seems to have changed over the course of 6.x
we need to explicitly check the version.

Fixes #8997

it's really dorked on [the documentation page](http://docs.ansible.com/ec2_elb_lb_module.html). This puts it in line with other modules.

Do not remove local role file if given on the commandline

attributes

Fixes #8594

Fixes #8998

Fixes #8983

Mention defaults subdirectory in a more visible way

Update playbooks_variables.rst

vsphere_guest module doc fix

All examples do not show it, so only someone reading the doc from
end to end would know about it.

using this (for testing purpose) :
  $ ansible-galaxy install COPYING
  - error: the file downloaded was not a tar.gz
  - COPYING was NOT installed successfully.
  - you can use --ignore-errors to skip failed roles.

this result in COPYING being erased, which is surprising for the user.
This also prevent erasing requirements.yml if someone use the wrong flag.
