Fix issues introduced by pylint/pep8 for dcmanager

This commit fixes some regressions caused by the merge with
master in the original commit.
1 - Small formatting changes to be more consistent with
    existing code;
2 - Removal of require_audit_flag that was mistakenly
    reintroduced during a rebase;
3 - Repositioning of eventlet.monkey_patch() so it
    happens before the other imports;
4 - Fix the admin IP conditional so it matches previous
    behavior;
5 - Change the determine_image_fields conditional so it
    matches previous behavior.

Test Plan:
1. Perform `tox` command
- Pass in py39, pylint, pep8:
