Subject: [PATCH 08/13] Removing INFLUXDB_HTTP_LOG from logparser usage/docs

this log format is likely soon going to be removed from a future
influxdb release, so we should not be recommending that users base any
of their log parsing infra on this.

-### Release Notes
-
-- `flush_jitter` behavior has been changed. The random jitter will now be
-evaluated at every flush interval, rather than once at startup. This makes it
-consistent with the behavior of `collection_jitter`.
-
-- All AWS plugins now utilize a standard mechanism for evaluating credentials.
-This allows all AWS plugins to support environment variables, shared credential
-files & profiles, and role assumptions. See the specific plugin README for
-details.
-
-- The AWS CloudWatch input plugin can now declare a wildcard value for a metric
-dimension. This causes the plugin to read all metrics that contain the specified
-dimension key regardless of value. This is used to export collections of metrics
-without having to know the dimension values ahead of time.
-
-- The AWS CloudWatch input plugin can now be configured with the `cache_ttl`
-attribute. This configures the TTL of the internal metric cache. This is useful
-in conjunction with wildcard dimension values as it will control the amount of
-time before a new metric is included by the plugin.
