This is a continuation of effor which transforms status widgets with buttons executing actions to separate status widget and action panels. This patch strips certificate status widget of its buttons and separates the actions to their own objects. Appropriate modifications are taken in host and service details facets. New certificate loader, facet policy and evaluator are introduced to make actions and status widget independent. On facet load event new certificate facet policy loads a certificate from result. Unfortunately results don't contain revocation reason so it also executes additional cert-show command to get the revocation reason. Policy store the certifacete to facet. It raises the certifacet_loaded event to notify certificate evaluator and status widget. Status widget updates its state. Certificate evaluater updates state and actions get disabled or enabled. https://fedorahosted.org/freeipa/ticket/2250
Ground rules on adding new schema Brand new schema, particularly when written specifically for IPA, should be added in share/*.ldif. Any new files need to be explicitly loaded in ipaserver/install/dsinstance.py. These simply get copied directly into the new instance schema directory. Existing schema (e.g. in an LDAP draft) may either be added as a separate ldif in share or as an update in the updates directory. The advantage of adding the schema as an update is if 389-ds ever adds the schema then the installation won't fail due to existing schema failing to load during bootstrap. If the new schema requires a new container then this should be added to install/bootstrap-template.ldif.
