commit 3f908e19a0422f9552d43e30762d93a8fc988ab2

s4-scripting: Remove repl_cleartext_pwd.py
This script was the precursor to newer samba-tool commands and no longer
works. The previous commits record some of the work to have it operate in
the
modern era, but keeping this around is more trouble than it is worth.
Use these commands instead:
samba-tool drs clone-dc-database --include-secrets
samba-tool user getpassword administrator --attributes=virtualClearTextUTF8
