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.

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)

Fixes #4723

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.
