`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)

When asking the quesiton "is my IPA server configured?" right now
we look at whether the installation backed up any files and set
any state. This isn't exactly precise.
Instead set a new state, installation, to True as soon as IPA
is restarted at the end of the installer.
On upgrades existing installations will automatically get this
state.
This relies on the fact that get_state returns None if no state
at all is set. This indicates that this "new" option isn't available
and when upgrading an existing installation we can assume the
install at least partly works.
The value is forced to False at the beginning of a fresh install
so if it fails, or is in a transient state like with an external
CA, we know that the installation is not complete.

ipa-server-install executes ipa-client-install with the --on-master
flag set, which causes the ipaclient.install.client.sssd_enable_ifp()
function to be called. This function configures sssd so that the
ipaapi user is allowed to access ifp. Any FreeIPA replica should also
have sssd configured like this, but in that case we cannot simply pass
the --on-master flag to ipa-client-install because it has other side
effects. The solution is to call the
ipaclient.install.client.sssd_enable_ifp() function from inside the
ipaserver.install.server.replicainstall.promote_sssd() function.

It was found that if an account was created with a name corresponding to
an account local to a system, such as 'root', was created via IPA, such
account could access any enrolled machine with that account, and the local
system privileges. This also bypass the absence of explicit HBAC rules.
root principal alias
-------------------
The principal "root@REALM" is now a Kerberos principal alias for
"admin". This prevent user with "User Administrator" role or
"System: Add User" privilege to create an account with "root" principal
name.
Modified user permissions
-------------------------
Several user permissions no longer apply to admin users and filter on
posixaccount object class. This prevents user managers from modifying admin
acounts.
- System: Manage User Certificates
- System: Manage User Principals
- System: Manage User SSH Public Keys
- System: Modify Users
- System: Remove Users
- System: Unlock user
``System: Unlock User`` is restricted because the permission also allow a
user manager to lock an admin account. ``System: Modify Users`` is restricted
to prevent user managers from changing login shell or notification channels
(mail, mobile) of admin accounts.
New user permission
-------------------
- System: Change Admin User password
The new permission allows manipulation of admin user password fields. By
default only the ``PassSync Service`` privilege is allowed to modify
admin user password fields.
Modified group permissions
--------------------------
Group permissions are now restricted as well. Group admins can no longer
modify the admins group and are limited to groups with object class
``ipausergroup``.
- System: Modify Groups
- System: Remove Groups
The permission ``System: Modify Group Membership`` was already limited.
Notes
-----
Admin users are mostly unaffected by the new restrictions, except for
the fact that admins can no longer change krbPrincipalAlias of another
admin or manipulate password fields directly. Commands like ``ipa passwd
otheradmin`` still work, though. The ACI ``Admin can manage any entry``
allows admins to modify other entries and most attributes.
Managed permissions don't install ``obj.permission_filter_objectclasses``
when ``ipapermtargetfilter`` is set. Group and user objects now have a
``permission_filter_objectclasses_string`` attribute that is used
by new target filters.
Misc changes
------------
Also add new exception AlreadyContainsValueError. BaseLDAPAddAttribute
was raising a generic base class for LDAP execution errors.

Previously in order to enable the LDAP profile subsystem
the ca_enable_ldap_profile_subsystem() would check the
current value of the profile subsystem class parameter in
CS.cfg. If the parameter was still set to the default value
(i.e. ProfileSubsystem), the code would change it to
LDAPProfileSubsystem.
There is a effort in PKI to clean up the profile subsystem
classes which may require changing the default value for
this parameter. However, this improvement is blocked since
the ca_enable_ldap_profile_subsystem() is implicitly assuming
that the default value will always be ProfileSubsystem.
This patch modifies the code such that instead of checking
for a specific value that needs to be changed, it will check
whether it has the desired value already. This mechanism
will reduce potential conflicts with future PKI improvements.

Commit 49cf5ec64b fixed a bug that
prevented migration from externally-signed to self-signed IPA CA.
But it introduced a subtle new issue: certmonger-initiated renewal
renews an externally-signed IPA CA as a self-signed CA.
To resolve this issue, introduce the `--force-self-signed' flag for
the dogtag-ipa-ca-renew-agent script. Add another certmonger CA
definition that calls this script with the `--force-self-signed'
flag. Update dogtag-ipa-ca-renew-agent to only issue a self-signed
CA certificate if the existing certificate is self-signed or if
`--force-self-signed' was given. Update `ipa-cacert-manage renew'
to supply `--force-self-signed' when appropriate.
As a result of these changes, certmonger-initiated renewal of an
externally-signed IPA CA certificate will not issue a self-signed
certificate.

In order to allow operators to still open Bind recursion, a new file is

file is not managed by the installer, meaning changes to it won't be

Since it's included at the very end of the main configuration file, it
