pip module: fix unexpected behavior when creating virtualenvs

Add ansible_sudo_pass hostvar support. Fixes #4323

fix for https://github.com/ansible/ansible/issues/4795 (incorrect changed result in cron module)

Ensure async terminates when time limit is not divisible by 5

Fixes #4485 add an ipv6 parameter to accelerate so that the daemon will bind to an ipv6 port instead of ipv4

Add a timeout to the synchronize module to prevent infinite hangs while waiting on passwords for misconfigured users

AWS_ACCESS_KEY misspelt in shared EC2 connection library

Couple of small typos

Fix code block quoting in documentation

Clarify cobbler.py usage and testing instructions

Fix for connect method parameter order

Changed parameter from 'user' to 'name' in the examples to coincide with...

Add double colons where necessary to get code blocks, not blockquotes.

The doc incorrectly advised executing the static inventory, not the `cobbler.py` script. Also fixes minor language issue.

Fix: ec2_eip connect method references module var that is not passed in

'easy_install' executable were still left behind and need to be removed
for the customizable 'executable' task argument to correctly work:

determining the correct 'easy_install' executable to use.
