DESKPROFILE: Introduce the new IPA session provider In order to provide FleetCommander[0] integration, a session provider has been introduced for IPA. The design of this feature and more technical details can be found at [1] and [2], which are the design pages of both freeIPA and SSSD parts. As there's no way to test freeIPA integration with our upstream tests, no test has been provided yet. Is also worth to mention that the name "deskprofile" has been chosen instead of "fleetcmd" in order to match with the freeIPA plugin. It means that, for consistence, all source files, directories created, options added, functions prefixes and so on are following the choice accordingly.

DP: Reduce Data Provider log level noise Certain operations are not supported with certain providers causing informational Data Provider log messages to be logged as errors or failures. This patch lowers the log level to reduce overall log noise and ensure only critical log messages are logged when a low debug_level value is used.

SUDO: Drop logic to disable the backend in case the provider is not set As sudo responder requires some period task in the backend, has been decided (a long time ago) to disable it in the backend unless it's explicitly configured. Following Pavel Březina's suggestion, as it's one of our main features, let's treat it exactly as we treat any other responder and in case the admins want to disable it they should explicitly use: "sudo_provider = None".

DP: Introduce new interface for backend Terminology: * Backend: Implemenation of domain * Data Provider: interface between backend and responders * Module: ldap/ipa/ad/... dlopened library that implements dp interface * Target: id/autofs/sudo/... functionality of module Benefits over current code: * data provider is a black box completely separated from backend * method handlers are just simple tevent requests on backend side * no need of spy on be_client * simplified and error proof adding of new responders * simplified adding of new methods * reply to D-Bus message is completely handled by DP code * each target can have several methods defined * properties can be added on objects * each method can have output parameters * modules now support constructor * improved debugging * clear memory hierarchy * ability to chain requests * type safe private data Reviewed-by: Sumit Bose <sbose@redhat.com> Reviewed-by: Jakub Hrozek <jhrozek@redhat.com> Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>
