Jason Kölker b7e894b196 Do not fail on notify when quantum and melange are out of sync.
This patch adds the `ignore_missing_network_data` flag which will log
exceptions rather than raising them when generating usage exists
notifications.

"""Cron script to generate usage notifications for instances neither created
nor destroyed in a given time period.
Together with the notifications generated by compute on instance
create/delete/resize, over that time period, this allows an external
system consuming usage notification feeds to calculate instance usage
for each tenant.
Time periods are specified as 'hour', 'month', 'day' or 'year'
hour = previous hour. If run at 9:07am, will generate usage for 8-9am.
month = previous month. If the script is run April 1, it will generate
usages for March 1 through March 31.
day = previous day. if run on July 4th, it generates usages for July 3rd.
year = previous year. If run on Jan 1, it generates usages for
Jan 1 through Dec 31 of the previous year.
