    Sync periodic_task from oslo-incubator

    This is more or less to get commit c63fd5a from oslo into the core
    projects which have several periodic tasks. Neutron has periodic tasks
    for L3, load balancing and metering agents to sync up state with the
    server and most don't have specific spacing values set which can lead to
    non-deterministic spacing of when the tasks run.

    Note that this does not include the gettextutils and log dependencies
    since there are not functional changes in those modules needed for the
    periodic_task changes synced in *and* more importantly, the changes
    to gettextutils and log require pervasive changes to neutron which
    should happen when neutron integrates with the oslo-i18n library for
    blueprint i18n--messages.

    Further note that this does not include jsonutils due to some
    issues introduced with a change for python 2.6 that impacts how strings
    are encoded with simplejson. The details for that issue are in bug
    1314129. The jsonutils changes are not related to the periodic_task
    changes being synced in so the dependency is not functionally required.

    The LbaasAgentManager extends PeriodicTasks but wasn't calling the
    parent class init function, which was causing failures since commit
    47c9d60 changed PeriodicTasks to init _periodic_last_run, so also
    fixed that here.

    Changes:

    c63fd5a Make unspecified periodic spaced tasks run on default interval
    f0dd798 Remove rendundant parentheses of cfg help strings
    fcf517d Update oslo log messages with translation domains
    051b9f3 Refactor unnecessary arithmetic ops in periodic_task
    674cdaf Refactor if logic in periodic_task
    b6b82c5 Use timestamp in periodic tasks
    47c9d60 Don't share periodic_task instance data in a class attr
    8b2b0b7 Use hacking import_exceptions for gettextutils._
