Fix expires

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

The NOSETESTS variable can be used to support customizing the nosetests
parameters.  This allows providing custom nose parameters such as
--with-coverage.

Minor readme tweaks since I haven't edited this in a while.
