- Update to final v2.0.0 release (bsc#1067341):
  + Compared to version 1.x, this release includes a completely rewritten
    storage engine, huge performance improvements, but also many backwards
    incompatible changes.  For more information, read the announcement blog
    post and migration guide:
  - https://prometheus.io/blog/2017/11/08/announcing-prometheus-2-0/
  - https://prometheus.io/docs/prometheus/2.0/migration/
  + Changes:
  * Completely rewritten storage layer, with WAL.  This is not backwards
    compatible with 1.x storage,  and many flags have changed/disappeared.
  * New staleness behavior. Series now marked stale after target scrapes
    no longer return them, and soon after targets disappear from service
    discovery.
  * Rules files use YAML syntax now.  Conversion tool added to promtool.
  * Removed count_scalar, drop_common_labels functions and keep_common
    modifier from PromQL.
  * Rewritten exposition format parser with much higher performance.  The
    Protobuf exposition format is no longer supported.
  * Example console templates updated for new storage and metrics names.
    Examples other than node exporter and Prometheus removed.
  * Admin and lifecycle APIs now disabled by default, can be reenabled via
    flags
  * Flags switched to using Kingpin, all flags are now --flagname rather
    than -flagname.
  + Features:
  * Remote read can be configured to not read data which is available
    locally.  This is enabled by default.
  * Rules can be grouped now.  Rules within a rule group are executed
    sequentially.

  * Add timestamp() function to PromQL.
  + Enhancements:
  * Remove remote read from the query path if no remote storage is
    configured.
