Kerberos service might request a ticket to itself on behalf of a user
to perform protocol transition, so-called S4U2Self extension defined
in [MS-SFU] specification. Processing of this request by KDC differs for
in-realm and cross-realm configurations.
Use SMB service to test S4U2Self performed against AD and IPA users.

cifs/... principal on SMB server side has NetBIOS name of the SMB server
as its alias. Test that we can actually initialize credentials using
this alias. We don't need to use it anywhere in Samba, just verify that
alias works.

Pylint is a static analysis tool and therefore, couldn't always
analyze dynamic stuff properly. Transformation plugins is a way
to teach Pylint how to handle such cases.
Particularly, with the help of FreeIPA own plugin, it is possible
to tell Pylint about instance fields having a duck-typing nature.
A drawback exposed here is that a static view (Pylint's) of code
should be consistent with an actual one, otherwise, codebase will
be polluted with various skips of pylint checks.
* added missing fields to ipatests.test_integration.base.IntegrationTest
* an attempt is made to clear `no-member` skips for ipatests
* removed no longer needed `pytest` module transformation

Test test_smb_mount_and_access_by_different_users was failing with message
```
kdestroy: Permission denied while initializing krb5
```
This happened because the previous test
`test_smb_access_for_ad_user_at_ipa_client` was calling the fixture
`enable_smb_client_dns_lookup_kdc` which was doing backup of krb5.conf
in a wrong way:
- mktemp (to create a temp file)
- cp /etc/krb5.conf to the temp file
- ...
- mv tempfile /etc/krb5.conf
This flow looses the file permissions, because mktemp creates a file
using the default umask, which results in -rw------- permissions.
The copy does not modify the permissions, and the mv keeps the
permissions from the source => /etc/krb5.conf now has -rw-------.

Add tests for following scenarios:
* running `ipa-client-samba --uninstall` without prior installation
* mount and access Samba share by IPA user
* mount and access Samba share by AD user
* mount samba share by one IPA user and access it by another one
* try mount samba share without kerberos authentication
* uninstall and reinstall ipa-client-samba

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.
