Ideally all files created during an IPA server installation are
removed by the uninstaller. Some files are purposefully left,
like token passwords, private keys, logs and more. Add an
allow list for those files.
Include a test to catch any additional files that may be created
and left behind.

`dnspython` 2.0.0 has many changes and several deprecations like:
```
> dns.resolver.resolve() has been added, allowing control of whether
search lists are used. dns.resolver.query() is retained for backwards
compatibility, but deprecated. The default for search list behavior can
be set at in the resolver object with the use_search_by_default
parameter. The default is False.
> dns.resolver.resolve_address() has been added, allowing easy
address-to-name lookups.
```
The new class `DNSResolver`:
- provides the compatibility layer
- defaults the previous behavior (the search list configured in the
system's resolver configuration is used for relative names)
- defaults lifetime to 15sec (determines the number of seconds
to spend trying to get an answer to the question)

For now Debian, Fedora, RHEL, etc. build BIND with 'native PKCS11'
support. Till recently, that was the strict requirement of DNSSEC.
The problem is that this restricts cross-platform features of FreeIPA.
With the help of libp11, which provides `pkcs11` engine plugin for
the OpenSSL library for accessing PKCS11 modules in a semi-
transparent way, FreeIPA could utilize OpenSSL version of BIND.
BIND in turn provides ability to specify the OpenSSL engine on the
command line of `named` and all the BIND `dnssec-*` tools by using
the `-E engine_name`.

While [1] did open recursion, it also opened widely a security flaw.
This patch intends to close it back, while allowing operators to easily
add their open configuration within Bind9.
In order to allow operators to still open Bind recursion, a new file is
introduced, "ipa-ext.conf" (path might change according to the OS). This
file is not managed by the installer, meaning changes to it won't be
overridden.
Since it's included at the very end of the main configuration file, it
also allows to override some defaults - of course, operators have to be
careful with that.

Scenario: install a replica with DNS, whose IP address is part of a
forward zone.
Currently, the replica installation fails because the installer is
trying to add a A/AAAA record for the replica in the zone
when setting up the bind instance, and addition of records in a
forward zone is forbidden.
The bind installer should check if the IP address is in a master zone
(i.e. a DNS zone managed by IdM, not a forward zone), and avoid
creating the record if it's not the case.
During uninstallation, perform the same check before removing the
DNS record (if in a forward zone, no need to call dnsrecord-del).
