Change CB (cache buster) to use 'cache' from the request

[krowvin]

There was some confusion on the swagger URL builder to what cb was.

This will remove the request to cache and bring the URL back to what it was before.

req.cache sets the browser cache, more on mdn's Request cache docs

headers[...etc] will keep the proxy/down the wire data sniffers in line with caching. (edge cache)

I did some testing on localhost by

1. Clicking execute in the swagger page to see each request NOT cache
2. fetch("http://localhost:8081/cwms-data/location/category") in the browser console to see the requests cache
3. Repeating 1. after 2 to see no-cache was working
4. fetch("http://localhost:8081/cwms-data/location/category", {cache: "no-cache"}) to mimic what swagger now does and confirming no "disk cache" in the network tab
