Fix the docs for glance_image.endpoint_type

The endpoint_type option was added in version 1.7,
so the docs need to state this.  Also the the description
is too brief.
zypper: handle lists of packages efficiently
Add support for filtering EC2 instances in dynamic inventory

This allows filtering out EC2 instances based on various different
filters including tags. As requested in 7480 it supports logical "OR"

Merge pull request #8988 from bbasleeper/bugfix_yum_module

Fix a bug causing yum module to not update to latest in some cases
Do not remove local role file if given on the commandline

using this (for testing purpose) :
  $ ansible-galaxy install COPYING
  - error: the file downloaded was not a tar.gz
  - COPYING was NOT installed successfully.
  - you can use --ignore-errors to skip failed roles.

this result in COPYING being erased, which is surprising for the user.
This also prevent erasing requirements.yml if someone use the wrong flag.
Mention defaults subdirectory in a more visible way

All examples do not show it, so only someone reading the doc from
end to end would know about it.
