This doesn't account for boto configs where e.g. RDS has one
default region and EC2 another - all will default to `ec2_region_name`.

However, this is just handy to allow an easy site wide default
region if existing configuration already relies on it.

Modules can be improved to mention this in the documentation and
turn off required=True where needed. But it works with `ec2`
and `ec2_vol` without change.

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)

* align packages in optdepends using spaces
* use double quotation marks only where it's needed
* unify usage of brackets sorrounding variables
* shorten pkgdesc (kudos to Fedora)

Clarify doc for get_url

Fixes #4633

Added module to handle rabbit policies [1]

Minor tweaks to simplify examples and documentation

rds module: add snapshot capabilities

Move a sentence from doc for the "force" option to that for the "dest" option.

This is accomplished by not setting the If-Modified-Since header,
and setting "cache-control: no-cache" instead. Note that if the
file content has not changed, the module will still report that
changed=false, as the md5's of the tmp file and existing file are
compared before swapping

Fixes #5104

Added -FF flag to rsync invocation in synchronize

synchronize module: Added existing_only options to skip creating new files on receiver

Fix slow ssh

Add support for --copy-links in synchronize

Fix missing quote mark in route53 doc example

Made a few things more consistent with the bulk of the other EC2
modules and removed an unnecessary check that is handled by
AnsibleModule

We break the read while loop after waiting "the end of the process" and
the pipes are empty, otherwise we do another select that waits all the
timeout.

fixed bug causing symlinks to fail in the host_vars, group_vars etc dire...

PlayBook: better error message

Enable changes to ttl of a record to be propogated to route53

Use /etc/rc.conf.local for sevice configuration on FreeBSD

Allow quoted strings as passwords in postgres_user

Revert "Fix for issue 5739. The copy module does not delete directories it will only unlinks symlinks."

This reverts commit b20dc4f5.

Clean up stray space at the end of a line after a period.
