registry.py -l user:password -r https://my-registry.tld with a 2.8.2 registry returns nothing.

with --debug:

[debug][funcname]: get_auth_schemes()
[debug][docker] Auth schemes found:['basic']

Checking with curl -u user:password 'https://my-registry.tld/v2/_catalog?n=10000 returns:

{"errors":[{"code":"PAGINATION_NUMBER_INVALID","message":"invalid number of results requested","detail":{"n":10000}}]}

This is caused by this commit where registry added a configurable limit of entries returned from /v2/_catalog that defaults to 1000.
