Fix Jenkins translation jobs

The -propose-translation-update and -upstream-translation-update
jobs do not update from transifex since our po files contain
duplicate entries where obsolete entries duplicate normal entries.

Remove all obsolete entries to fix the jobs.

Allowed nested resource metadata in POST'd samples

Fixes bug 1302664

Previously, posting samples with nested metadata caused the mongo
driver to fail on the embedded period in a metadata key.

Now, we explicitly unwind the flattened resource metadata before
publishing the sample.

More accurate meter name and unit for host load averages

Fixes bug 1307482

Previously, the SNMP reported load averages were misleadingly metered
as percentage utilizations.

Now, these samples include a meter name and unit that more accurately
reflect their true meaning - i.e. an exponentially-damped moving average
of the number of running or runnable processes.
