    Implement filter support in driver backends
    
    Currently filtering is only done at the controller level, leading to
    performance issues since we are not using native filtering capabilities
    of any of the underlying backends (e.g. SQL, LDAP). This patch enables
    such support.
    
    This patch also creates the foundation for implementing truncation of
    lists to size set by the cloud provider as well as providing pagination
    support.  However, both these capabilities are implemented as separate
    patches.
    
    Limitations:
    
    - The LDAP backend does not yet support for filtering, leaving it to the
      controller level.  LDAP support will be added in a separate patch
    - The inexact filters are disabled, pending api review of the changes,
      which is targeted for IceHouse
    - Filtering for service, endpoint and policy is left at the controller
      level, since these operations are not considered performance issues.
    
    SecurityImpact: Please review for Potential for Sql Injection attacks.
