KFSPTS-37856 remove un-needed server references and convert to use central maven repo and github artifacts

[jhulslander]

some new exclusions were added as they were libraries we don't need and there were problems being able to get them from Maven.
Please double check that the dependencies aren't needed.

retest this please

This is ready for review but please do NOT merge this yet. We need to cooridinate this change.
Each developer much update their Maven settings file. Jenkins needs to use the new settings file. The Develop branch, CEMI branch, and master branch will need the POM file changes to build

Please also review https://confluence.cornell.edu/x/WulgH paying attention to the update Maven instructions.

I confirmed that I was able to get KFS to build locally with this branch and the settings.xml file changes in place. (I ran out of time today to check whether KFS would launch, though.) I also updated the Confluence instructions to include Windows setup steps.

However, there were a few items I wanted to get clarity on, and it would be helpful to have another Mac developer test out this setup.

My concerns have been addressed, so this can be merged once our team determines an appropriate time to move things forward. If another Mac developer wants to perform some local testing of this, we could also wait for that testing to be completed.
