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"
instead of "AND" on the provided list of filters.
Exit with rc 1 if role doesn't exist/is not found

fixes #8823
	modified:   bin/ansible-galaxy
Make ansible-galaxy work as expected

This change fixes hg galaxy roles
Roles also get installed if roles path is missing, which
the tests currently require (fixes #8950)
Allow github style ssh repo names
vsphere_guest module doc fix
Update playbooks_variables.rst

very small and minor addition, but I couldn't find anywhere that answered this (now obvious) question I had of whether or not facts could also be yaml files.
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.
