A draft PR replacing _ls_real, it correctly works for find/walk which will correct glob's issues. It currently overwrites the httpfs version of _ls_real. This was done because otherwise _find, _walk, and _glob would also need to copied and added to pelicanfs which was giving me some bugs, but I can change it if you want it differently.

There are also TODOs in the comments for pieces that I am still working on.

Things that still need to be done/tested:

• Unit tests: I want to write extensive unit tests for all these effected functions to ensure things still work
• All the unit tests work locally, but the webdavhostname doesn't work for the unit tests. I'm sure it's just a matter of adding some sort of test server response to fix.
• I need to test and ensure auth and token provisions in _ls_real and account for edge cases as well as ensure it gives what we expect when detail=False
• Because httpfs's versions of find is calling our version of _ls_real, the full url names are being retained in the detailed returns. I need to do some more extensive end to end tests to ensure this doesn't break things. Especially with Harsha's intake catalogues, etc.

EDIT: Apologies for the many pushes, the rebase I did before this wasn't fully done properly. (So many linter fixes)
