Sometimes, `blkid` will incorrectly return no information about a block
device, even if it exists and has a valid filesystem. This causes the
*filesystem* module to fail if *force=no*. Instructing `blkid` to use
`/dev/null` as a cache file will force it to rescan the block device on
each run, making results more consistent.

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.

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.
```
---
- name: remove any existing lv=one of vg=main
lvol: lv=one vg=main state=absent
- name: remove any existing lv=two of vg=main
lvol: lv=two vg=main state=absent
- name: check to see if lv=one of vg=main exists
lvol: lv=one vg=main state=present
ignore_errors: true
register: lvol_result0
- name: Assert that we will get a "No size given."
assert:
that:
- "'No size given.' in lvol_result0.msg"
- name: create lv=one of vg=main sized 30g
lvol: lv=one size=30g vg=main state=present

Bugfixes:
* the remote_src param was not being converted to a boolean correctly,
resulting in it never being used by the module as the default behavior
was remote_src=True (issue #5581)
* the remote_src param was not listed in the generic file params, leading
to a failure when the above bug regarding remote_src was fixed
* the delimiter should always end with a newline to ensure that the file
fragments do not run together on one line
Fixes#5581
