Several plugins need restarting the DS (or they currently do
an external bind).
Rather than disabling plugins (possibly partially), refuse
to run them when run as an unprivileged user.
This means running ipa-ldap-updater as non-root requires specifying
a list of files, and omiting the --upgrade and --plugins options.

For security reasons, dynamic updates are not enabled for new DNS
zones. In order to enable the dynamic zone securely, user needs to
allow dynamic updates and create a zone update policy.
The policy is not easy to construct for regular users, we should
rather fill it by default and let users just switch the policy
on or off.

bind-dyndb-ldap persistent search queries LDAP for all DNS records.
The LDAP connection must have no size or time limits to work
properly.
This patch updates limits both for existing service principal
on updated machine and for new service principals added
as a part of DNS installation.

With a publicly accessible DNS tree in LDAP, anyone with an access
to the LDAP server can get all DNS data as with a zone transfer
which is already restricted with ACL. Making DNS tree not readable
to public is a common security practice and should be applied
in FreeIPA as well.
This patch adds a new deny rule to forbid access to DNS tree to
users or hosts without an appropriate permission or users which
are not members of admins group. The new permission/aci is
applied both for new installs and upgraded servers.
bind-dyndb-ldap plugin is allowed to read DNS tree without any
change because its principal is already a member of "DNS
Servers" privilege.

When updating from 2.x we need to add nsDS5ReplicatedAttributeList and
nsDS5ReplicatedAttributeListTotal if they aren't present.
If nsDS5ReplicatedAttributeList is present and doesn't contain memberof
then we want to add it.

New features in bind-dyndb-ldap and IPA DNS plugin pulled new
attributes and objectclasses. ACIs and permissions need to be
updated to allow users with appropriate permissions update
these attributes in LDAP.
This patch updates the ACI for DNS record updates and adds one
new permission to update global DNS configuration.

SSH public key support includes a feature to automatically add/update
client SSH fingerprints in SSHFP records. However, the update won't
work for zones created before this support was added as they don't
allow clients to update SSHFP records in their update policies.
This patch lets dns upgrade module extend the original policy
to allow the SSHFP dynamic updates. It updates only original
policy, we don't want it to overwrite custom user policies.

Provide a way to specify BIND allow-query and allow-transfer ACLs
for DNS zones.
IMPORTANT: new bind-dyndb-ldap adds a zone transfer ability. To
avoid zone information leaks to unintended places, allow-transfer
ACL for every zone is by default set to none and has to be
explicitly enabled by an Administrator. This is done both for new
DNS zones and old DNS zones during RPM update via new DNS upgrade
plugin.

There are two reasons for the plugin framework:
1. To provide a way of doing manual/complex LDAP changes without having
to keep extending ldapupdate.py (like we did with managed entries).
2. Allows for better control of restarts.
There are two types of plugins, preop and postop. A preop plugin runs
before any file-based updates are loaded. A postop plugin runs after
all file-based updates are applied.
A preop plugin may update LDAP directly or craft update entries to be
applied with the file-based updates.
Either a preop or postop plugin may attempt to restart the dirsrv instance.
The instance is only restartable if ipa-ldap-updater is being executed
as root. A warning is printed if a restart is requested for a non-root
user.
Plugins are not executed by default. This is so we can use ldapupdate
to apply simple updates in commands like ipa-nis-manage.
