Thi permit to simplify the command line to use by using
a sensible default, and so reduce the number of incorrect
possible choices and setup needed. Among potential
incorrect choices is using a fixed directory in /tmp, which
could be problematic with a setup whose access is not
properly restricted.

add_group module: strip trailing/leading whitespace from comma-separated group names

git: Always return the before/after revisions, even in check mode.

Improve change detection in mysql_variables

mysql_variables bindly executes a SET var = value query even when
the variable already has the requested value.

With this patch the query is executed only if the current value is
different to the requested one.

Various standardization to the proposed gce_storage module to bring things in line with updates to the S3 module.
Some typo fixes.

Further testing required.

support for google cloud storage module

adding Google Compute Engine modules and inventory plugin

Fix typo

Do key validation only when key is provided

key_id is optional, the previous code didn't handle the case of key_id
not specified

Make errors which get thrown during template rendering more user-friendly

Remove keys regardless of the options

ignore src when file module state=absent

Properly handle DEFAULT section with ConfigParser in ini_file modules

Fix 'ansible-doc -l' runtime error following commit 4430d0f5

skip "module" not found as plugin, id est directory

when searching for a plugin only look for a regular file

apt_key: Validate key_id and accept a leading '0x'

s3: better check for walrus

Check for Walrus endpoint by looking to see if the endpoint is not AWS.

This fixes a bug where the user specifies an AWS endpoint via S3_URL,
but the code interprets it as Walrus and then fails.

Ensure non-root users can read arguments file when using sudo_user and non-standard modules

The return values from check mode and non-check mode should match in all cases,
except when a SHA-1 hash is used as version, as there is no way to check if it
is a valid hash using `git ls-remote`.

Also, to accomodate this change, the force flag for the reset function has been
removed so that we can do the checking in main.

This allows the module to return the before/after revisions in all cases.

The functions either return rc=0 or call fail_json themselves.

This removes ambiguity at the expense of slight backward incompatibility.

Non-standard modules must read in the arguments file in order to access their arguments, however, when this file is transfered to the remote host it may only have the permissions 600.  This means that using sudo and sudo_user will result in permission denied errors when attempting to read the arguments file.

This patch fixes #4438 by explicitly forcing the arguments file to be world readable before executing the module.

Fix TestInventory class by explicitly using /bin/bash
