Ipf

This release fixes how IPF handles an edge case that can occur in lmod_cache files (spiderT.lua) where the version of a module might not be a string.

It also formalizes the lupa dependency needed for reading lua files.

* New option for the modules workflow for sites using Lmod. IPF can now be configured to use an lmod cache file instead of a MODULEPATH as the source of module information to be published
* RPM built with python 3.11 which should enhance compatibility
* fix for init script: su command needed a -c argument
* IPF documentation revised for clarity and completeness
* Default for support contact no longer references an XSEDE service

Fixes issue 2 by having the default extmodules workflow treat each directory in MODULEPATH as a top level directory, all of whose subdirectories are semantically significant, and part of the inferred module name.

The old behavior is still available by using the --modules-recurse option for ipf_configure when configuring the workflow.

This default behavior no longer excludes module files that exist directly in the top level directory (as was the old default behavior). To keep this behavior, use the --ignore_toplevel_modulefiles when configuring the workflow.
