Christian Heimes e6d560af66 Make IPADiscovery available in PyPI packages
The ipaclient PyPI package does not ship the ipaclient.install
subpackage. The ipaclient.install.ipadiscovery module with IPADiscovery
is now available as ipaclient.discovery, so it can be used by consumers
of PyPI packages.

The module ipaclient.install.ipadiscovery provides a backwards
compatibility shim with deprecation warning.

Christian Heimes a3934a211d Use new LDAPClient constructors
Replace get_ldap_uri() + LDAPClient() with new LDAPClient constructors
like LDAPClient.from_realm().

Some places now use LDAPI with external bind instead of LDAP with simple
bind. Although the FQDN *should* resolve to 127.0.0.1 / [::1], there is
no hard guarantee. The draft
https://tools.ietf.org/html/draft-west-let-localhost-be-localhost-04#section-5.1
specifies that applications must verify that the resulting IP is a
loopback API. LDAPI is always local and a bit more efficient, too.

The simple_bind() method also prevents the caller from sending a
password over an insecure line.

Christian Heimes 917d81b832 Allow HTTPd user to access SSSD IFP
For smart card and certificate authentication, Apache's
mod_lookup_identity module must be able to acess SSSD IFP. The module
accesses IFP as Apache user, not as ipaapi user.

Apache is not allowed to use IFP by default. The update code uses the
service's ok-to-auth-as-delegate flag to detect smart card / cert auth.

Christian Heimes 8b0f3595fd Allow ipaapi user to access SSSD's info pipe
For smart card authentication, ipaapi must be able to access to sss-ifp.
During installation and upgrade, the ipaapi user is now added to
[ifp]allowed_uids.

The commit also fixes two related issues:

* The server upgrade code now enables ifp service in sssd.conf. The
  existing code modified sssd.conf but never wrote the changes to disk.
* sssd_enable_service() no longer fails after it has detected an
  unrecognized service.

Rob Crittenden e59ee6099f Fix misleading errors during client install rollback
Some incorrect errors are possible if a client installation
fails and a configuration rollback is required.

These include:

1. Unconfigured automount client failed: CalledProcessError(Command
['/usr/sbin/ipa-client-automount', '--uninstall', '--debug']
returned non-zero exit status 1: '')

Caused by check_client_configuration() not returning the correct
return value (2).

2. WARNING: Unable to revert to the pre-installation state ('authconfig'
tool has been deprecated in favor of 'authselect'). The default sssd
profile will be used instead.
The authconfig arguments would have been: authconfig --disableldap
--disablekrb5 --disablesssdauth --disablemkhomedir

If installation fails before SSSD is configured there is no state
to roll back to. Detect this condition.

3. An error occurred while removing SSSD's cache.Please remove the
cache manually by executing sssctl cache-remove -o.

Again, if SSSD is not configured yet then there is no cache to
remove. Also correct the missing space after the period.

Rob Crittenden 8af6accfa5 Retrieve certificate subject base directly instead of ipa-join
The subject base is used as a fallback to find the available
CA certificates during client enrollment if the LDAP connection
fails (e.g. due to new client connecting to very old server) and
for constructing the subject if a certificate is requested.

raw=True is passed to config-show in order to avoid parsing
the server roles which will fail because the services aren't
marked as enabled until after the client installation is
successful on a master.

ipa-join providing the subject base via stderr was fragile and
would cause client enrollment to fail if any other output was
included in stderr.
