removing some unusued files.  Paramiko alt was an experiment to attempt pipeline for paramiko, ssh_old is the non-pipelining-supported earlier
version of the OpenSSH transport, which is configurable now and unified.

This reverts commit 6f1a58ab.

Properly match existing security group

mysql_db: Emphasize target is on remote host. List supported file types.

If we don't care about `vpc_id` then neither should the code.

From the documentation it is not immediately clear that the 'target'
option refers to a location on the remote host. This change emphasizes that.
In addition to .sql files, .bz2 and .gz files are supported for dumps and
restores. This is now documented.

Module to create EC2 snapshots

rax module: Use regex start and end of string with name base filters

Fix setup module to gather facts from PowerPC Macs.

Rename flatten function.

flatten(x) is used a lot in the various lookup plugins where in each it is slightly different. This is to make this name slightly more unique.

Fix fails on ubuntu due to missing /etc/motd

Tests functional on centos6, ubuntu1204 and ubuntu1310 now.

Some systems that we are testing on may not have /etc/motd. So we need to create a file that we can control and use that for the further tests.

Fixes #5869

lookup_plugins: loop over hashes

Tests good with the global variables:
```
users:
  alice:
    name: Alice
    id: 12345
  luna:
    name: Luna
    id: 23456
```

and playbook tasks:
```
- name: Print records.
  debug: msg="User {{ item.key }} is {{ item.value.name }}  {{ item.value.id }}"
  with_dict: users
```

Create a lookup plugin named dict that can be used to loop over hashes.
It converts a dict into a list of key-value pairs, with attributes named
"key" and "value."  Also adds a brief explanation and simple example to
the docs.

Fixes #5869

 Fixed up merge for the lvol module.

Conflicts:
	library/system/lvol

If you try to resize a lvol to the current size return a changed=False and don't fail.

Fix expires

This addresses GH-5165 and adds the ability to check if a lvol exists.

The tests for this don't fit nicely into the current integration tests so they are below.

```
