Refactor LH Benefits Claims code

[jerekshoe]

Summary

Lighthouse has determined that we should only have one set of client credentials that we use for all applications on va.gov. This pull request cleans up the code related to LH Benefits Claims to reflect this decision. I have left in code that allows for having specific credentials per LH service, as LH doesn't currently provide us with a good way to create a set of sandbox credentials that has access to all services currently.
