HBAC Access Time

IPA commands now can be defined in these classes:
 - ipa_command: a single IPA command
 - ipa_batch_command: a batch command for executing multiple commands
   on the server side using the new batch plugin

The dialog boxes for adding and removing entries have been refactored:
 - ipa_dialog: base class for dialog boxes
 - ipa_adder_dialog: generic adder dialog box
 - ipa_deleter_dialog: generic deleter dialog box
 - ipa_association_adder_dialog: adding entity association
 - ipa_association_deleter_dialog: removing entity association

Dialog boxes for adding/deleting HBAC users, hosts, services, and
sourcehosts are implemented using the association dialog boxes.

The dialog box for adding access time is implemented using ipa_dialog
and currently contains only a text field. This will be replaced with a
custom dialog box in a separate patch.

The dialog box for removing access time is implemented using the
generic deleter class because it's not an association. Removing multiple
access times is implemented using batch operations.

New test data files for access times have been added.
