Added paging on search facet.

The search facet has been modified to support paging on most entities
using the --pkey-only option to get the primary keys and a batch command
to get the complete records.

Paging on DNS records is not supported because a record may appear as
multiple rows. The following entities do not have --pkey-only option:
Automount Key, Self-Service Permissions, Delegation.

The search and association facet have been refactored to reuse the
common code from the table facet base class.
