93bbe2d219 tests: Minor code cleanups to confidential_attr test
+ fix a couple of flake8 warnings
+ add some extra code comments (particularly around the cases where the
  child class overrides a particular method, to avoid confusion when
  browsing the code).
+ assert_not_in_result() was duplicated (it's only needed for the deny
  ACL tests)
+ skip redundant if in dirsync's assert_search_result() (it always has
  to use the base-DN - we never pass it this as an args).

7070aa384b CVE-2018-10919 tests: Add extra test for dirsync deleted object corner-case
The acl_read.c code contains a special case to allow dirsync to
work-around having insufficient access rights. We had a concern that
the dirsync module could leak sensitive information for deleted objects.
This patch adds a test-case to prove whether or not this is happening.

The new test case is similar to the existing dirsync test except:
- We make the confidential attribute also preserve-on-delete, so it
  hangs around for deleted objcts. Because the attributes now persist
  across test case runs, I've used a different attribute to normal.
  (Technically, the dirsync search expressions are now specific enough
  that the regular attribute could be used, but it would make things
  quite fragile if someone tried to add a new test case).
- To handle searching for deleted objects, the search expressions are
  now more complicated. Currently dirsync adds an extra-filter to the
  '!' searches to exclude deleted objects, i.e. samaccountname matches
  the test-objects AND the object is not deleted. We now extend this to
  include deleted objects with lastKnownParent equal to the test OU.
  The search expression matches either case so that we can use the same
  expression throughout the test (regardless of whether the object is
  deleted yet or not).

This test proves that the dirsync corner-case does not actually leak
sensitive information on Samba. This is due to a bug in the dirsync
code - when the buggy line is removed, this new test promptly fails.
Test also passes against Windows.

375f48f779 CVE-2018-10919 tests: Add tests for guessing confidential attributes
Adds tests that assert that a confidential attribute cannot be guessed
by an unprivileged user through wildcard DB searches.

The tests basically consist of a set of DB searches/assertions that
get run for:
- basic searches against a confidential attribute
- confidential attributes that get overridden by giving access to the
  user via an ACE (run against a variety of ACEs)
- protecting a non-confidential attribute via an ACL that denies read-
  access (run against a variety of ACEs)
- querying confidential attributes via the dirsync controls

These tests all pass when run against a Windows Dc and all fail against
a Samba DC.
