Bump to version 0.9.1

Bump to 0.9.0. (#443)

Bump to 0.8.17

This release contains a memory-leak fix for our kafka dependency
as well as a change to prometheus internal telemetry. The bulk of
the diff is in automatic upgrades to our crates.

  * 12520e9 :: cernan.sinks.prometheus.aggregation.reportable as SET, not SUM (#435)
  * ed4339e :: Upgrade rdkafka to 0.11.4 (rustrdkafka to 0.16.0) (#436)

Bump to 0.8.16

This release includes improvements to the programmable_filter's
error handling, enabling of the logging subsystem before configuration
file parsing happens and quieting of the kafka sink when reporting
hangup errors.

  * e78bf80 :: Add a context that ignores "Receive failed: Disconnected" error logs
  * 8b171f7 :: Remove extra lazy_statics
  * 408722d :: Add error handling to calling lua functions
  * 604d7d7 :: Enable the logging subsystem before config parsing

Bump to 0.8.15

This release corrects an issue with the Elasticsearch sink losing
tags. We expect memory efficiency of the logging subsystem will also
be improved. The json_encode filter is now hooked up and the kafka
sink has seen its error handling improved.

  * 29a6db5 :: Promote `MessageTimedOut` to an error that will be retried
  * c9c6f01 :: json_encode filter configuration
  * 1a8fa81 :: Fix the lack of tags in ES sink, introduced in 0.8.13

Bump to 0.8.14

This release contains a host of small fixes to cernan. The wavefront
sink live-stall is, we believe, addressed. We also no longer emit
Elasticsearch debug messages at error level, which turned out to
cause a feedback cycle for some users.

  * a14146e :: Remove redundant extern
  * 68a63bb :: Emit debug, not error, in ES sink
  * ac3d847 :: Address one possible WF sink live-stall cause

Bump to 0.8.13

This release incorporates significant improvements to cernan and is
a recommented upgrade. In particular, cernan now uses hopper 0.4.
This update of hopper is _significantly_ more efficient, being only
about 3x slower than built-in MPSC while maintaining resource
quotas. These quotas are now exposed as configuration to cernan. An
experimental kafka sink is also added but care should be taken with
its use. Mike Lang has been landing improvements to the programmable
filters and it is hoped they are now more useful.

Cernan's baseline acceptance test is now 272k statsd PPS, held in
10Mb. This is up from 45k statsd PPS at 150Mb.

  * dcbeb7d :: Reduce high PPS memory consumption
  * 4d2d118 :: Update hopper to 0.4
  * d10d195 :: Added json_encode filter
  * ecc2fdf :: Kafka sink introduced

Bump to 0.8.12

This release contains a bug fix for 0.8.11, which double-counted
its internal telemetry. Anyone using 0.8.11 and the internal source
is recommended to update. Elsewise, you're more or less blind.

  * dac169c :: Don't double-count internal telemetry

Bump to 0.8.11

This release switches our internal telemetry from a Set aggregation
to Sum, removing the reset to zero between flushes. In release
mode cernan will wrap-around when the counters are fully saturated.
Don't saturate your counters in debug mode. We also correct
telemetry in the kinesis sink.

  * c6abe6b :: Switch internal telemetry to Sum from Set
  * f50a892 :: Fixes Kinesis Internal Telem. on Batch Success

Bump to 0.8.10

This release improves warnings around truncation of bin_width when
flush_interval is lower than bin_width for a given sink. The native
source will no longer space explode if the far-side does something
goofy, panics have been removed in the statsd/tcp sources and kinesis
is now more durable to errors.

  * d0bb60b :: Warn if Wavefront bin_width > flush_interval
  * 0f4756b :: Resolve space explosion in the native source
  * 44fcabc :: Removes Undesirable Panics From statsd/tcp Sources
  * 8c3084f :: Improves Durability of Kinesis Sink.
