Added port documentation to postgresql_db and postgresql_user.

Addresses #5739 and cleans up copy.py

Support for -a to accept a file with test-module

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.

A fix for uri module regarding following redirects. The old behavior would follow redirects either way. This change clarifies the functionality and makes it a bit more explicit. Comparing the old behavior to the new 'yes' == 'all', 'no' == 'safe' and now 'no' will not follow any redirects. Historic behavior is still supported and documented with a push to the new values.

Add exact_count and count_tag to the ec2 module.

Confirmed that these are small changes to the docs that help with the clarity.

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
