The code for hostname in ipa-join is simplified. Now the hostname is

`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)

were still IPA 2.0.x servers in use so this delegation was

EPN stands for Expiring Password Notification. It is a standalone
tool designed to build a list of users whose password would expire
in the near future, and either display the list in a machine-readable
format, or send email notifications to these users.
EPN provides command-line options to display the list of affected users.
This provides data introspection and helps understand how many emails
would be sent for a given day, or a given date range.
The command-line options can also be used by a monitoring system to alert
whenever a number of emails over the SMTP quota would be sent.
EPN is meant to be launched once a day from an IPA client (preferred)
or replica from a systemd timer.
EPN does not keep state. The list of affected users is built at runtime
but never kept.

NIST SP 800-63-3B sets a recommendation to have password length upper bound limited in A.2:
https://pages.nist.gov/800-63-3/sp800-63b.html#appA
Users should be encouraged to make their passwords as lengthy as they
want, within reason. Since the size of a hashed password is independent
of its length, there is no reason not to permit the use of lengthy
passwords (or pass phrases) if the user wishes. Extremely long passwords
(perhaps megabytes in length) could conceivably require excessive
processing time to hash, so it is reasonable to have some limit.
FreeIPA already applied 256 characters limit for non-random passwords
set through ipa-getkeytab tool. The limit was not, however, enforced in
other places.
MIT Kerberos limits the length of the password to 1024 characters in its
tools. However, these tools (kpasswd and 'cpw' command of kadmin) do not
differentiate between a password larger than 1024 and a password of 1024
characters. As a result, longer passwords are silently cut off.
To prevent silent cut off for user passwords, use limit of 1000
characters.
Thus, this patch enforces common limit of 1000 characters everywhere:
- LDAP-based password changes
- LDAP password change control
- LDAP ADD and MOD operations on clear-text userPassword
- Keytab setting with ipa-getkeytab
- Kerberos password setting and changing

Introduces new utility to configure Samba on an IPA domain member.
The tool sets up Samba configuration and internal databases, creates
cifs/... Kerberos service and makes sure that a keytab for this service
contains the key with the same randomly generated password that is set
in the internal Samba databases.
Samba configuration is created by querying an IPA master about details
of trust to Active Directory configuration. All known identity ranges
added to the configuration to allow Samba to properly handle them
(read-only) via idmap_sss.
Resulting configuration allows connection with both NTLMSSP and Kerberos
authentication for IPA users. Access controls for the shared content
should be set by utilizing POSIX ACLs on the file system under a
specific share.
The utility is packaged as freeipa-client-samba package to allow pulling
in all required dependencies for Samba and cifs.ko (smb3.ko) kernel
module. This allows an IPA client to become both an SMB server and an
SMB client.
