Boost::urls::format

Boost 1.82 dropped a lovely new toy, boost::urls::format, which is a lot
like our urlFromPieces method, but better in that it makes the resulting
uris more readable, and allows doing things like fragments in a single
line instead of multiple.  We should prefer it in some cases.

Tested:
Redfish service validator passes.
Spot checks of URLs work as expected.
Unit tests pass.
