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.

When DCERPC clients use Kerberos authentication, they use a service
ticket to host/domain.controller because in Active Directory any
service on the host is an alias to the machine account object.
In FreeIPA each Kerberos service has own keys so host/.. and cifs/..
do not share the same keys. It means Samba suite needs to have access to
host/.. keytab entries to validate incoming DCERPC requests.
Unfortunately, MIT Kerberos has no means to operate on multiple keytabs
at the same time and Samba doesn't implement this either. We cannot use
GSS-Proxy as well because Samba daemons are running under root.
As a workaround, copy missing aes256 and aes128 keys from the host
keytab. SMB protocol doesn't use other encryption types and we don't
have rc4-hmac for the host either.

Implement the import and export handlers for Custodia keys as external

Except for DMLDAP, handlers no longer run as root but as handler

Dogtag PKI typically takes around 10 seconds to start and respond to
requests. Dogtag uses a simple systemd service, which means systemd is
unable to detect when Dogtag is ready. Commands like ``systemctl start``
and ``systemctl restart`` don't block and wait until the CA is up. There
have been various workarounds in Dogtag and IPA.
Systemd has an ExecStartPost hook to run programs after the main service
is started. The post hook blocks systemctl start and restart until all
post hooks report ready, too. The new ipa-pki-wait-running script polls
on port 8080 and waits until the CA subsystem returns ``running``.
