Fraser Tweedale 01c534c229 cert-request: avoid internal error when cert malformed
When executing cert-request, if Dogtag successfully issues a
certificate but python-cryptography cannot parse the certificate, an
unhandled exception occurs.  Handle the exception by notifying about
the malformed certificate in the response messages.

Rob Crittenden 32c64a78ce Fix cert-find for CA-less installations
Change eb6d4c3037 deferred the
detailed lookup until all certs were collected but introduced
a bug where the ra backend was always retrieved. This generated a
backtrace in a CA-less install because there is no ra backend in
the CA-less case.

The deferral also removes the certificate value from the LDAP
search output resulting in only the serial number being displayed
unless --all is provided. Add a new class variable,
self.ca_enabled, to add an exception for the CA-less case.

Stanislav Laznicka 61605d28d8 parameters: introduce CertificateSigningRequest
Previously, CSRs were handled as a Str parameter which brought
trouble to Python 3 because of its more strict type requirements.
We introduce a CertificateSigningRequest parameter which allows to
use python-cryptography x509.CertificateSigningRequest to represent
CSRs in the framework.

Stanislav Laznicka 5a44ca6383 Create a Certificate parameter
Up until now, Bytes parameter was used for certificate parameters
throughout the framework. However, the Bytes parameter does nothing
special for certificates, like validation, so this had to be done
for each of the parameters which were supposed to represent a
certificate.

This commit introduces a special Certificate parameter which takes
care of certificate validation so this does not have to be done
separately. It also makes sure that the certificates represented by
this parameter are always converted to DER format so that we can work
with them in a unified manner throughout the framework.

This commit also makes it possible to pass bytes directly during
instantiation of the Certificate parameter and they are still
represented correctly after their conversion in the _convert_scalar()
method.

Christian Heimes 3064b890e2 Conditionally import pyhbac
The pyhbac module is part of SSSD. It's not available as stand-alone
PyPI package. It would take a lot of effort to package it because the
code is deeply tight into SSSD.

Let's follow the example of other SSSD Python packages and make the
import of pyhbac conditionally. It's only necessary for caacl and
hbactest plugins.

I renamed convert_to_ipa_rule() to _convert_to_ipa_rule() because it
does not check for presence of pyhbac package itself. The check is
performed earlier in execute(). The prefix indicates that it is an
internal function and developers have to think twice before using it
in another place.

This makes it much easier to install ipaserver with instrumented build
of Python with a different ABI or in isolated virtual envs to profile
and debug the server.
