Added resource element to allow container managed

authentication. This is necessary to allow it to be referenced in the
attribute resolver.
Changed to ContainerManagedConnection

Removed the ApplicationManagedConnection and replaced it with a
ContainerManagedConnection by referencing the declared resource in idp.
xml
Moved idp.xml into a template file

The file idp.xml has been changed into a template file and moved to a
templates folder to allow group_vars variables to be inserted into the
file.
Changed task from copy to template module

As idp.xml is now a template, the corresponding task that was
responsible for copying the file to the right place has now been changed
to use the template module.
Fixed issue with missing quotes around name

Name variable assignment in the resource element was missing quotes.
This issue has now been rectified.
