pulp to pulp syncs fail with 405 on /pypi

[jlsherrill]

Trying to sync one pulp server from another (or even one remote from another on the same instance), results in a 405 when accessing /pypi

"POST /pulp/content/Default_Organization/Library/custom/python/python2/pypi HTTP/1.1" 405 226 "-" "bandersnatch 4.4.0 aiohttp XML-RPC client

The sync doesn't error, but no content is synced

Pulp to Pulp sync is still in tech preview and currently you can't fully sync from another Pulp instance without specifying the includes list. Behind the scenes Bandersnatch uses xmlrpc calls to get the full package list from the remote (typically PyPI), but we don't support the xmlrpc endpoints currently. I haven't looked into how difficult it would be to actually support them, but there are other options like parsing the simple pages for packages present. Here is the note about the current implementation:

pulp_python/pulp_python/app/tasks/sync.py

Lines 191 to 195 in 47f22a3

	"""
	If we reach here, then the Mirror most likely doesn't support XMLRPC.
	Could raise an exception or try to manually find all the packages from the index page,
	Or just keep packages_to_sync empty and have the sync do no work
