Merged uapprove playbook into idp playbook

Merging the two playbooks should eliminate redundancy and allow a more
streamlined install process.
Merged uapprove version of web.xml template file

into idp's version of web.xml template file. This eliminated redundancy
and allows a more streamlined install process.
Removed the uapprove role from ansible

The uapprove role is no longer needed as most of its functionality has
been merged into idp.
Moved over all of the uapprove role's files

As the functionality of the uapprove role has been merged into the idp
role, the files have to be moved over as well.
