Jinja extensions adds features to the jinja2 templating engine. This
patch allows module loading for the templating engine vian an
ansible.cfg configuration key (jinja_extensions).
The default behaviour doesn't change (no module loading).
Requested modules can be added coma separated in ansible.cfg
Adds whitespace handling in jinja_extension config
Added whitespace handling in jinja_extension configuration directive, so
things stay safe if user adds spaces around comas in the directives
list.
Adds config example for jinja_extensions
Added config example with multiple extentions for jinja_extensions
Hash variables are currently overriden if they are redefined. This
doesn't let the user refine hash entries or overriding selected keys,
which can, for some, be a desirable feature.
This patch let the user force hash merging by setting the
hash_behaviour value to "merge" (without the quotes) in ansible.cfg
However, by default, ansible behaves like it always did and if any value
besides "merge" is used ("replace" is suggested in the example ansible.cfg
file), it will also behave as always.
If PasswordAuthentication is enabled (which is the default) ansible
will spawn (multiple) ssh's with a password-prompt which corrupts
the terminal, and cannot be properly used.
So it is better to not allow for password-based authentication using
-c ssh. The result is that authentication fails but Ansible
continues to work
