`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)

The helper function ipalib.util.check_client_configuration() now
considers a client configured when either:
* confdir is overridden (e.g. with IPA_CONFDIR) and the conf_default
file exists.
* confdir is /etc/ipa, /etc/ipa/default.conf exists and client
sysrestore state exists.
The check for sysrestore state is faster than checking for the presence
of the directory and presence of files in the directory. The sysrestore
state is always presence. sysrestore.index may be missing if no files
were backed up.

Client connections no longer override TLS version range and ciphers by
default. Instead clients use the default settings from the system's
crypto policy.
Minimum TLS version is now TLS 1.2. The default crypto policy on
RHEL 8 sets TLS 1.2 as minimum version, while Fedora 31 sets TLS 1.0 as
minimum version. The minimum version is configured with OpenSSL 1.1.1
APIs. Python 3.6 lacks the setters to override the system policy.
The effective minimum version is always TLS 1.2, because FreeIPA
reconfigures Apache HTTPd on Fedora.

On Linux systems the length limit for hostnames is hardcoded

Solaris, for example, allows 255 characters, and DNS allows the
total length to be up to 255 (with each label < 64).
Add a knob to allow configuring the maximum hostname length (FQDN)
The same validators are used between hosts and DNS to apply
the knob only when dealing with a FQDN as a hostname.
The maxlen option is included so installers can limit the length
of allowed hostnames when the --hostname option is used.

Up until now, Bytes parameter was used for certificate parameters
throughout the framework. However, the Bytes parameter does nothing
special for certificates, like validation, so this had to be done
for each of the parameters which were supposed to represent a
certificate.
This commit introduces a special Certificate parameter which takes
care of certificate validation so this does not have to be done
separately. It also makes sure that the certificates represented by
this parameter are always converted to DER format so that we can work
with them in a unified manner throughout the framework.
This commit also makes it possible to pass bytes directly during
instantiation of the Certificate parameter and they are still
represented correctly after their conversion in the _convert_scalar()
method.

NSSConnection is therefore replaced with Python's
