Overview panels use too wide date range as default

[Timur Sufiev]

Standard default date range for Overview panels (Project and Admin) is starting from first day of current month till today. This default causes long response times on environments with a lot data to crunch, which is worsened by the fact that Users are always redirected to Overview panel by default (even if they don't want to see the Usage Stats).

    Reduce the default date range on Overview panel to 1 day

    First, the default default date range used on Overview panel is made
    configurable (setting OVERVIEW_DAYS_RANGE). Second, its default value
    is set to 1 day. Changing the default behavior is aimed to improve
    load time of the default page in the presence of large amounts of
    data. If OVERVIEW_DAYS_RANGE setting is explicitly set to None, the
    behavior remains the same - the default date range is from the
    beginning of the current month until today.

Can this be backported to stable/liberty?

[Timur Sufiev (tsufiev-x)]

AFAIK, stable/liberty is now for security fixes while the current bug is not related to security.

This issue was fixed in the openstack/horizon 10.0.0.0b2 development milestone.
