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.

```
---

- 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
  register: lvol_result1

- name: Assert that we made changes."
  assert:
    that:
      - "lvol_result1.changed == True"

- name: check to see if lv=one of vg=main exists
  lvol: lv=one vg=main state=present

      - "lvol_result5.changed == True"

- name: create lv=two of vg=main sized 30G when already exists at 30G
  lvol: lv=two size=30g vg=main state=present

Merge branch '5853-python-2.5-apt_repository-fix' of https://github.com/timurbatyrshin/ansible into timurbatyrshin-5853-python-2.5-apt_repository-fix

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

Correct assert and add with_items test

Vault rewrite, pass 1

Typo/Grammar fix.

allow ansible_ssh_private_key_file to be templated (thanks to benno)

This tests clean with the new integration tests.

Fix typo in guide_rax

replace test 'wget' package with 'hello' package

Remove obsolete module development docs

In the route53 module, documenting that TXT and SPF values must be surrounded by quotes

must be surrounded by quotes.

Otherwise you get a cryptic error message from Route 53.

Allow custom nosetest parameters
